Pride Month – overblown rhetoric must not be allowed to trump reality – Andrew MacGregor offers welcome clarity.

What has actually happened

The Supreme Court did not remove rights from trans people. It clarified which legal characteristic protects which interest.

The Equality Act 2010 contains nine protected characteristics. Two of them are relevant here: sex and gender reassignment. For years, ambiguity existed about how these interacted – particularly whether a trans woman (i.e. a man) with a Gender Recognition Certificate should be treated as a woman for every purpose under the Act, including access to single-sex services. The Supreme Court, unanimously, said no: for the purposes of the Act, “sex” means biological sex. A GRC does not alter that for equality law purposes.

Trans rights remain protected

This is a legal clarification, not a legal amputation. The characteristic of gender reassignment, which protects anyone who is proposing to, undergoing, or has undergone a process of gender reassignment – remains fully intact. Trans people cannot be discriminated against in employment. They cannot be harassed. They cannot be refused a service without lawful justification. They cannot be treated with hostility or contempt and have no legal recourse. All of that remains, unchanged, in statute.

What has been clarified is narrower: where a service is genuinely single sex, it operates on the basis of biological sex. But even here, the new Code of Practice imposes an obligation – providers who exclude trans people from single-sex spaces must ensure that alternative provision is available. Failing to do so risks being found to have discriminated on grounds of gender reassignment. Trans people must not be left without facilities at all.

This is balance, worked out in law over several years of litigation, consultation, and parliamentary process. It is not erasure.

Sex is not a spectrum

Underlying the legal clarification is a biological reality that the law has now, belatedly, been forced to acknowledge: humans cannot change sex. Sex in humans is not a spectrum, a social construct, or a matter of self-identification. It is a biological classification, determined at conception by chromosomes and expressed through reproductive anatomy, that is fixed and immutable throughout a person’s life. No surgical procedure, no hormonal treatment, and no legal certificate alters the underlying biological reality.

Every human being is innately either male or female. This is not a contested fringe position. It is the consensus of biology, medicine, and now, UK law.

Intersex variations do not negate the reality of binary sex

The most common challenge raised against this position involves people with Differences of Sexual Development (DSDs) sometimes called intersex conditions. These are genuine medical variations: chromosomal patterns such as XXY (Klinefelter syndrome), conditions affecting hormone receptors, or anatomical variations present from birth. They deserve sensitive and respectful medical and social care. But they do not, in fact, undermine the binary nature of biological sex.

DSD conditions are variations within the male/female binary, not evidence against it. A person with an XXY chromosome pattern is not a third sex – they are a male with a chromosomal variation that affects development. A person born with ambiguous anatomy is not outside the sex binary, they have a condition that complicates the expression of their biological sex. The existence of variation within a category does not dissolve the category. We do not conclude that height has no meaning because some people are unusually tall or short.

This matters to the legal debate because much of the “erasure” rhetoric rests on the implicit premise that sex is so fluid or contested that anchoring rights to it is arbitrary or cruel. It is neither. Recognising that sex is real, binary, and immutable — and that legal protections organised around it serve legitimate purposes is not an attack on anyone. It is a statement of fact.

Human Rights are NOT absolute – and that isn’t a threat either

Much of the political rhetoric around this issue treats “human rights” as a trump card that ends all argument. But this misunderstands how human rights actually work in domestic law, under the Human Rights Act 1998, and in the European Convention on Human Rights to which the UK remains a signatory.

With very few exceptions, human rights are qualified, not absolute. The right to freedom of expression under Article 10 does not protect incitement to racial hatred. The right to freedom of assembly under Article 11 does not mean marches can take place anywhere at any time regardless of public order. The right to private and family life under Article 8 must be balanced against competing public interests.

Trans rights are still protected – but they do not eliminate women’s rights

Equality rights operate in exactly the same way. The Equality Act itself has always permitted single-sex services as a lawful exception to the general prohibition on sex discrimination, provided the exclusion is a proportionate means of achieving a legitimate aim. That proportionality test has not gone away. It applies to decisions about single-sex spaces with renewed clarity. It means that a blanket, arbitrary, or vindictive exclusion of trans people from all public life would not be lawful. But it also means that a women’s domestic abuse refuge, a rape crisis centre, or a hospital ward can operate on a single-sex basis when there is good reason to do so.

This is the architecture of a mature human rights framework: competing rights, balanced proportionately, with none permitted to simply override another by assertion. The complaint that this framework has been applied to the tension between sex-based rights and trans rights is not an argument that human rights are being violated. It is a complaint that one set of interests did not win outright, which is not the same thing.

The section 28 comparison simply doesn’t hold water

The comparison to Section 28 of the Local Government Act 1988 is not merely rhetorical excess, it is historically and legally backwards.

Section 28 was a law that created a new prohibition where none had existed. It barred local authorities from “intentionally promoting homosexuality” or publishing material with the “intention of promoting homosexuality” and from promoting the teaching in any maintained school of the acceptability of homosexuality as a “pretended family relationship.” It had no balancing provision. It contained no proportionality test. It imposed no duty of alternative provision. It simply told public bodies that a category of people (gay men and lesbians) could not be positively acknowledged in certain public contexts.

The chilling effect was profound and deliberate. Teachers could not address homophobic bullying for fear of legal liability. Libraries removed books. Young LGB people were left isolated and without support. It was the law as a weapon of social stigma.

Now compare the legal developments last year and this year:

  • They did not create a new prohibition. They clarified the meaning of an existing statute.
  • They do not remove a protected characteristic from trans people. They confirm that gender reassignment remains a full and operative protection.
  • They do not permit blanket exclusion of trans people from public life. They require proportionality and mandate alternative provision.
  • They were reached through years of democratic and judicial process, including a unanimous Supreme Court ruling and extensive public consultation.
  • They impose obligations on service providers towards trans people, not merely permissions to exclude.

Section 28 told the state to treat gay people as though they did not fully exist. The Equality Act framework, as now clarified, tells service providers that they have duties towards trans people and that leaving them without any provision is itself unlawful. These are not comparable situations. Invoking Section 28 as an analogy does not illuminate the present situation – it distorts it, and it trivialises what Section 28 actually meant and did to real people.

Why the language used matters

None of this is to suggest that trans people face no difficulties in the current environment. The polarisation of this debate has generated genuine hostility, and the people most exposed to that hostility are ordinary trans individuals going about their lives, not the campaigners or politicians arguing loudly on all sides.

But the solution to a difficult social environment is not to mischaracterise the law. When activists describe legal clarity as “erasure,” they are not informing the public, they are alarming it. When political parties describe the reaffirmation of existing Equality Act provisions as an “attack on human rights,” they are not protecting those rights, they are debasing the currency of rights language in ways that will, over time, weaken everyone’s ability to invoke it meaningfully.

The harm of performative politics

There is a specific harm worth naming here that goes beyond rhetorical sloppiness: the performative political statement issued purely for audience management.

In recent weeks, party spokespeople across the political spectrum have queued up to express solidarity with trans people in terms calibrated for applause rather than accuracy. These statements typically involve some version of the claim that trans people are being persecuted, that the law has been weaponised against a vulnerable minority, and that the speaker stands firmly against this outrage. They are then followed by no concrete legislative proposal, no legal challenge, and no actual policy commitment – because, in reality, there is nothing to oppose. The law is functioning as it is supposed to function.

This kind of performative solidarity is not merely useless. It is actively harmful. It tells trans people (many of whom are already anxious and confused about their legal position) that they are under siege in ways that are not accurate. It raises fear without cause. It substitutes the emotional signal of outrage for the practical information that trans people actually need. It obscures the reality that their protections remain, that they have legal recourse if discriminated against, and that the system is not their enemy.

Politicians who genuinely care about the wellbeing of trans constituents would spend less time issuing alarming press releases and more time clearly explaining what the law does and does not say. The gap between those two approaches tells you a great deal about whether the motivation is concern for trans people or the simpler pleasure of performing virtue to an approving audience.

Good advocacy informs. It empowers. It tells people what their rights are and how to exercise them. Advocacy that exists primarily to generate emotional heat, amplify a sense of victimhood, and signal the advocate’s own righteousness is not advocacy for trans people. It is little but advocacy for the advocate.

The law exists for everyone – whether they understand it or not

The Equality Act has nine protected characteristics because Parliament recognised that human dignity takes many forms, and that protecting one person’s rights sometimes requires careful thought about how they interact with another’s. That careful thought – expressed in statute, tested in courts, refined in guidance – is not hostility. It is the legal system doing exactly what it is supposed to do.

Trans people in the UK have legal protections. Those protections are real. They are named. They are enforceable. The biological reality that sex is binary and immutable is not a weapon pointed at trans people (however uncomfortable they are with their own sex), it is the factual foundation on which a coherent legal framework can be built that protects everyone. Calling the clarification of that framework an act of erasure is not advocacy. It is sensationalist nonsense and the people it claims to speak for deserve something considerably better than nonsense.

    Much said by Andrew here is accurate and relevant, but there is a fundamental flaw in his reasoning. He has been partial in his reporting of the April 2025 Supreme Court judgment, which said that “references in the EA 2010 to “man”, “woman” and “sex” were references to biological sex (meaning “the sex of a person at birth”).” It is a matter of course that except in rare cases of substantial external sexual ambiguity, new-born infants are not haplotyped to find their chromosomal makeup, nor scanned to assess their internal sexual anatomy. Rather the sex reported at birth is generally that agreed upon in the birthing room, between the midwife and/or the obstetrician and the parent or parents. Assignment of sex is based on the appearance of the external genitalia, and the responsible parent is then left to report this within 42 days (21 days in Scotland) to the registrar of births, a system that has been in place since the 19th Century.

    It is that sex designation which the Supreme Court referred to, not a definition of sex based on sex chromosomes. That is why in certain DSD cases a child can be registered at birth as a female, be found as an adult during infertility investigations to be in possession of only XY chromosomes and yet be unable to legally change her registered birth to male under current guidance used by the registrars in England. Before same sex marriages were allowed in law the same female (for that is how the law sees her) could have been legally married, and even after the discovery of her XY haplotype, the marriage would not have been legally annulled. This is only one example of the numerous potential complicated interactions between sex chromosomes, external sexual phenotype, the possession of internal sexual organs including but not limited to gonads, and civil life. That is why case law in DSD and Transgender cases, which goes unmentioned by Andrew, struggled to define what biological sex actually was, leading up to the ECtHR case of Goodwin versus the United Kingdom 2002.

    The problem was, following that ECtHR judgement, the Gender Recognition Act 2004, in considering the apparent confusion about what constituted biological sex, decided to put all the eggs in one basket (as it were). The psychological perception of sex alone was given hegemony. That was a category error which I have written about in another piece which will hopefully be published shortly. That category error is open to a human rights challenge in itself, but such a challenge is not served by declaring another category error (sex is all about the chromosomes) as its replacement. And using that false binary to then state that sex is thus de facto binary and not a spectrum is a generalisation fallacy. For sure, considerations about sex chromosomes need to be part of the root and branch review now needed, but I very much doubt chromosomes will survive on their own as the go to criteria.

      If I understand your argument correctly, the main problem is that babies with DSD can be assigned to the wrong sex at birth and this can not be changed, in that it will remain their “biological “ sex even if it is subsequently found that, in term of underlying chromosomes, an error was made. No doubt some tidying up of the law is required in this area, but this does not represent a “fundamental flaw” in the argument . Indeed you say that basing the definition of biological sex on chromosomes alone is a category error, without explaining your reasoning. What criteria would you use to distinguish between male and female ?
      The Goodwin case is a red herring as it concerns the rights of a person who had reassigned, male to female , rather than a person whose underlying biology was ambiguous.
      In practice, the tension in this debate is between the individuals gender identity and their underlying biology. I would hope that were a trans woman, wrongly assigned male at birth and fundamentally female, to present herself in a female space, common sense would prevail.

        The problem with your challenge to my “fundamental flaw” argument, is that it begs the question. Your opening statement presumes that an error would have been made because the correct allocation of sex is on the basis of sex chromosomes, but the flaw questioned that very basis. Yes, it is a category error as much as self-ID.

        The current “sex assigned at birth” status is on the basis of external sexual genitalia and that is also a category error if it does not allow for a revision when other factors come to light. In this respect “sex” is not immutable if by sex you mean chromosomes (a conclusion based on a begged question), but sex can be amended, where it is sensible to do so. The problem is, the whole issue of DSD, and how that area relates to a legal determination of sex, has been historically under-legislated, I suspect this has been because it has always been a matter of discomfort to those asked to do so. Rather it is buried in the grey literature and documents not open to the public, and guidance to registrars differs across the UK. I agree that “some tidying up” is needed, but that is not a matter of clearing out under the bed, rather trying to give Plyushkin’s house a makeover. And yes, Goodwin always was a red herring. I discuss these points in another article in process.

        You hope that were trans woman, wrongly assigned male at birth and fundamentally female, to present herself in a female space, common sense would prevail. That is an admirable sentiment, but your scenario is under-described and thus hard to give a single answer on. I could give dozens of DSD permutations of that scenario, which might give very different answers.

        I tend to prefer the case of someone with a tetragametic macrochimerism (they have both XX and XY cells in their body, in various granularities of mosaicism). Such a person is the product of a mixed-sex dizygotic twinning event where the eggs have fused. In one case series 44% were phenotypically male or female, 66% had various DSDs, but of course both groups relate only to reproductive development. They could have a fully XY reproductive system, but an XX nervous system (or vice versa). Or both could be a complete admixture. In reality, we do not know the prevalence of this condition, although an upper bound could be as high as 1 in 352 live births (my own modelling). It is not tested for except in rare instances. How then do these people map to your scenario?

        What then determines male and female? Any examination of the case law on this demonstrates how difficult that actually can be. In the end it is a matter of consensus, but a consensus based on sound philosophical considerations, and not the hubris of politicians sticking it in the eye of the opposition. That is why the Davey/Goodwin proposal of a cross-party examination of all this is actually quite sensible. It may just end out not quite as they have envisioned it.

      2. Chris, No one. Not a single person ever is ‘assigned’ a sex at birth. Sex is identified (or misidentified) and that identification is recorded.
        It’s increasingly rare that children are misidentified in respect of their sex at birth and even in the rare circumstances it occurs, the misidentification becomes obvious at the individual develops through puberty or during tests for conditions that are generally co-morbid.

        In terms of Richard’s point. Once again, he has gone off-piste, and extended the conversation into philosophical debate, however, to respond with more detail. First of all, thank you for your detailed and genuinely informative response. The point about registered sex at birth versus chromosomal sex is well made, and I accept that the Supreme Court’s definition operates on the former rather than the latter. It is however indirectly noted in the article in the following paragraph. “The most common challenge raised against this position involves people with Differences of Sexual Development (DSDs) sometimes called intersex conditions. These are genuine medical variations: chromosomal patterns such as XXY (Klinefelter syndrome), conditions affecting hormone receptors, or anatomical variations present from birth. They deserve sensitive and respectful medical and social care. But they do not, in fact, undermine the binary nature of biological sex.” That last point can be summed up in the expression ‘the exception does not make the rule’…
        It seems to me, that you have attributed to the article a position it does not hold nor intend. Nowhere does this piece argue that biological sex reduces to chromosomes alone. It says sex is determined at conception by chromosomes and expressed through reproductive anatomy, which is a compound definition, not a chromosomal one. The DSD section was included precisely to anticipate the objection you raise, and it makes the specific argument: that variations within a category do not undermine or negate that category. You don’t address that argument. You do provide further and genuinely fascinating examples of DSD complexity, tetragametic macrochimerism is a case in point, but it is a DSD in that it creates potential ambiguity of genital presentation, but it is a genetic disorder. To repeat though, biological complexity, however intricate, does not by itself refute the points raised in the piece and it’s important to note that edge cases do not negate the general pattern noted above. . The point that ‘we do not conclude that height is meaningless because some cases are unusual’ stands unaddressed.
        I think the most important point here though is that the core of the piece is not really about the definition of biological sex at all. It is about three other things: whether the Section 28 comparison holds water (it does not, for the reasons set out concisely and at length); whether trans people retain legal protections under the Equality Act (they do, via gender reassignment as a fully operative characteristic, and with duties imposed on service providers where the PC does not generally apply); and whether performative political rhetoric is actively harming the trans people it claims to serve by misrepresenting their legal position. Your reply does not engage with any of those three arguments.

        DSDs are legislated for generally in the Equality Act 2010 via multiple protected characteristics. I don’t think it is fair to say that they are any more under-regulated than menopause, or fertility treatments. I also do not agree that the Davey/Goodwin statement does any more than play to a small section at the expense of women. The Liberal Democrats brought the Equality Act 2010 to the statute book and ensured the guidelines for its implementation were delivered to end users. It now seems that they wish to end the defining biological traits for men and women, not for the benefit of the tiny number of people with DSDs, but to benefit those self identifying as the opposite sex for whatever reason. A position that fundamentally undermines women’s rights, and erodes the support needed for trans people.

          Andrew is technically correct as the process after birth is clinical identification and then civil registration. The word assigned is a compression of that process, though one that the NHS uses in sex and gender considerations. Of course the objection Andrew raises does not address the point of my rebuttal.
          https://service-manual.nhs.uk/content/inclusive-content/sex-gender-and-sexuality

          The identification process is almost always no more than the neonatal inspection in the birth room. If there are indeterminate genitalia then karyotyping is recommended, but that is about 0.2% of live births. Andrew’s “increasingly rare” observation needs to be evidenced, because he appears to have an understanding of NHS practice that is not present on the ground. Equally the misidentification might, but does not always present at puberty. The examples I have given are within that post-puberty bracket.

          I accept that tetragametic macrochimerism might feel a little “off piste” because not many people have heard of it. My point was to demonstrate the complexity of the situation, give and indication that it might actually not be that rare, and essentially undermine the binary “Its all XX or XY” trope. I alluded to many other potential examples, and avoided giving them because this page is not an Encyclopedia of DSDs.

          These counterfactuals are not off piste, they demonstrate the fallacy of the primary assertion. If then we are to enter into “No True Scotsman” territory, where one regresses to “a man is XY” and “a woman is XX” and everything else is immaterial, then that is all fair dinkum, but only if you are then willing to entertain a third sex category that incorporates “all the others.” Or perhaps keep it to two and then have an adult discussion about how variant karyotypes and sex phenotypes are ultimately, in total, “assigned.”

          Now that is a conve to be had.

        2. Richard Hopkins avatar
          Richard Hopkins

          Andrew, now that your comment is up in full, I will withdraw the conve comment and address the remainder of your points.

          I did detect the nuance in your original article but unfortunately it was , as you say, “indirectly noted.” The point you made was opaque and for many readers, the bottom line was likely that chromosomes were your focus, the repetition of binary being why. Yes you introduced the concept that things were more complex, but I cannot see where you then made any other statement as to how reduction to a biological binary was defined. Rather it remained a tautological argument that sex was binary, because there were male and female, and that is only two, thus binary.

          My unfortunate typo probably didn’t help in understanding my own rejoinder, and I meant to say that sex is immutable if chromosomal sex is the definition, and so apologies for the double negative creeping in there. But it is only immutable if such a criterion is accepted. The courts have debated the mutability of sex in the face changes to the phenotype through surgery and hormone treatment, and so it starts to get legally complex at that point. You and I might not agree on this definition of change, but we have to be mindful of how the courts have reasoned it.

          Yes, the exception does not make the rule. You say that chromosomes and reproductive anatomy “are a compound definition,” but you do not actually proffer any rule to except to, or what degree of exception is tolerable before the binary threshold is crossed. Hence the reader is left with a confusion about what point you are making. I have to admit, in my own confusion, regression to the chromosomes seemed the only binary you could settle on (although your Klinefelter’s example confused even that).

          Perhaps if you could set out clearly what your definition of a male and a female actually is, such that the binary encompasses all possibilities, the fog might lift. Saying “edge cases do not negate the general pattern” suggests to me that you are adopting a stereotypical or prototypical approach, which is fine, but then you need rules to assign the edge cases, and I have not seen them offered. I did not address your comment that ‘we do not conclude that height is meaningless because some cases are unusual’ because it is not directly analogous to this subject.

          Finally you suggest that DSD’s are no more under-regulated than menopause, or fertility treatments. This is far from the point I was making. I was discussing the guidance to the registrars for the amendment to birth certificates. I challenge you to find that guidance in its original documented form. It is not in statutory law.

          As to the Davey/Goodwin letter, I think we share a concern about their motive, but I made it clear that I believe the outcome of a legislative review could actually backfire.

    Thank you Andrew. Your article sheds light in an area where we often find only heat. I particularly appreciate your discussion of performative advocacy.

    I think the point you’re looking for when people bring up DSDs is the continuum fallacy: the existence of people with true DSDs, where determining their sex at birth might be incorrect or not immediately obvious, is about 1 in 5,000 births. I’m not sure how many people it remains an issue for as they get older. The bigger question is why this is brought up. Exceptions exist where a very small number of people, due to rare conditions, might not adequately be able to use the correct male or female facilities; however, dismantling the whole system and allowing any male into a women-only space based on self-ID is non sequitur reasoning.

    1. Richard Hopkins avatar
      Richard Hopkins

      The problem with the word continuum is that it suggests in some minds a normal distribution, which patently is not the case in sex determination. The reality, if you approach the classification problem using discriminant function analysis, is that a distinct bimodal distribution would be found, the two historical sex categories. But on that axis there will be cases between the two modes, admittedly rare (but a lot less rare if chimerism is taken into account). These are people with DSDs. Historically a line was drawn between the modes, essentially on the appearance of the external genitalia, and people were assigned on that basis. However that then brings up cases which are the subject of much debate nowadays, because they can be detected, such as a person identified and raised as a female, who excels at sports, and is then found to have XY chromosomes. That then becomes a big issue for many, no matter how rare that occurrence might be, as the case of Caster Semenya has shown (though confidential medical records remain just that).

      It does not follow, as you say, that the whole system should be dismantled. But the historical keeping of such DSD states off the agenda, out of “shame,” has not helped. People with such XY DSD cases have quietly been getting on with their lives, as have many others with DSDs, in whatever sex class they were assigned at birth. The issue then is how to define sex classes, and then how to determine which class the edge cases belong in. And this is made more complex because the dividing lines might be situation specific. Biological reductionism to single elements clearly is not the way to do this. That was the failing of the GRA. That is also the fallacy of the “it’s all about sex chromosomes” approach. We need to take a Wittgensteinian “families” approach where the line is rationally drawn on multiple factors, and we should be open to the debate that edge cases might need some legal registration of their own (separate to or superimposed on the traditional two sex classes).

    Practically every law or legal definition involves problems. Crimes peter out into nuisances. There are blurred lines and grey areas. The Supreme Court applied the principle that words in an act should mean the same in every clause. It might have applied the “nuisance” principle and said that words should be interpreted differently in different contexts. At the end of the day, especially in cases of conflict of rights, an arbitrary ( arbitrary is not the same as capricious) rule has to be accepted.
