Supreme Court ruling: can women’s groups still choose to allow trans women?

104 replies

Blackdow · 20/04/2025 12:53

I’m just looking for someone to explain it to me. Sorry 🤦‍♀️.

Now that’s it’s been clarified in law than trans women do not come under the “women” category in the equality act, so we can use the single sex exemption to keep them out without fear of being sued, can place still choose to allow them?

For instance, a sexual assault support group for women or a woman’s group of any kind was previously being told they had to allow trans women as the equality act was being misrepresented. Now, the single sex exemption can be used properly so trans women can be told no. But what if they group wanted to allow them? Is the single sex exemption optional? Or do they now have to follow it? I’m just trying to make sure I understand it.

My phrasing might have been off, what I was referencing to is that a newborn girl doesn't have a uterus that has eggs and can get pregnant yet. Its only as they grow does that process occur.

"This is extraordinarily rare." And yet it happens. I mention the fact that some with Swyer syndrome can give birth without help to point out that they do in fact exist (science is about specificity if it doesn't fit exactly then the categories have to be changed/updated). That doesn't disprove my point. Medically speaking, there are enough people who fit into the "intersex" category, some people without even knowing it unless they got their genes checked, that they can't be considered outliers anymore. The medical system is based on outdated assumptions of what characteristics apply to which sex that it leaves swaths of women (even biological women) without help. It's what has allowed intersex babies to have their bodies surgically altered for the "comfort" or their parents and for the wider society.

I know I've gotten into a tangent, but I think the medical and legal system needs a drastic overhaul at the very least to recognise intersex individuals. If third world countries can do it, why can't we?

And yet it happens. I mention the fact that some with Swyer syndrome can give birth without help to point out that they do in fact exist (science is about specificity if it doesn't fit exactly then the categories have to be changed/updated).

No, you misunderstand. People with Swyer’s giving birth with help is exceedingly rare. People with Swyer’s do not have ovaries so it’s impossible for them to conceive, let alone give birth.

Gosh my phrasing is off again. Sorry about that, I will clarify further I meant 'at birth/as a newborn, the eggs are unable to move to the uterus yet, and they are unable to get pregnant". I was attempting to as clear as I could and was going to mention "during puberty" but interestingly, its as soon as a female begins ovulating which can occur long before puberty (that is something I just found out). Anyway, thank you for letting me know my phrasing was off, that was a blunder on my part.

So you’ve just found out females (are you defining females - seeing as you think it is rather difficult?) ovulate before puberty. You’re clearly not a biologist then.

So ‘I’m a scientist’ doesn’t really wash does it.

Do you disagree with Prof Robert Winston when he says that if you have an SRY gene and functional testosterone receptors then you are male and if not you are female ?

Yes I disagree. I have read research of those who agree with his argument and those that disagree and find the argument against his more sound, not to mention in his public appearances he seems to parrot misinformation about key social and scientific topics. He has obvious bias, and from my research, hasn't participated in any modern research papers in opposition or in agreement with him.

I would not be happy going to what I was told by advertising was single sex to then have a trans woman man in there!!

Ponderingwindow · 27/04/2025 17:32

If they want to provide support to women and transwomen, then advertising as a single-sex women’s group seems short-sighted. There will be transwomen that do not know the group is open to them.

clarity would not only help women who want a single sex group avoid this group, it would help one of the populations they want to serve.

So you’ve just found out females (are you defining females - seeing as you think it is rather difficult?) ovulate before puberty. You’re clearly not a biologist then.

So ‘I’m a scientist’ doesn’t really wash does it.

My area of expertise is mainly in biology and biochemistry. While I knew majority of females reach sexual maturity during puberty (as is the case for humans and most mammals), and how puberty impacts the body, I assumed that puberty was the catalyst for fertility since it's when periods begin (since that's the school of thought I operate under, since generally, ovulation and puberty occur in tandem). However, I remembered a few cases of children getting pregnant as young as 4 (a horribly dark subject) and assumed it was due to early puberty. However, I do stand corrected, as while ovulation "typically" begins during puberty, that isn't always the case.

I am a scientist, and scientists can have bias and scientists can be wrong. That is how different schools of thought occur. I am always learning on the job and actively look to broaden my horizons. I previously operated under the assumption that sex was binary in my younger years before my worldview was changed.

Unfortunately, scientifically speaking, binary means they have to be one or the other. Someone's sex is defined by a host of sexual characteristics; chromosomes, physical characteristics, gene expression and hormones. Someone who isn't expressly on one side of the 'binary' or the other with all characteristics are termed as outside the binary or intersexed (oversimplification but I would be writing paragraphs upon paragraphs if I didn't simplify). Most modern minds posit that sex is bimodal (two peaks, one representing male and the other female characteristics where any given person might be on the peaks or anywhere in between).

Especially considering as newborns doctors only check one of 4 characteristics that define sex it leaves much to be desired in the medical field. Some people who were defined female sex at birth might not even be if their other characteristics are checked. Also I wouldn't call 1.7% (of confirmed intersexed individuals) of 8 billion people 'disordered', that's too high of a population to scientifically be considered outliers.

Yes that is what binary means, and that is what sex is. There are two sexes, male and female. You cannot name a third sex because there isn't one. This is because there is no evolutionary need for one.

You confuse the binary of sex itself, with the various different ways we define or determine a living things sex.

There is a very small proportion of humans (and by small I mean lower than 0.001%) in which our knowledge has not yet reached a level where we could definitively determine their sex (those with severe cases of ovotesticular disorder or some form of mosaicism for example). This doesn't mean that they aren't either male of female, or in between the two. It's simply that our understanding is not at that level yet.

Sexual characteristics are obviously bimodal. No one is arguing that they aren't.

What you are saying is that someone with a 7 inch penis is more male than someone with a 5 inch penis, and that is simply ridiculous.

If your definitions of male and female are so narrow that they exclude anything that reproduces sexually then that is the problem, because there is no third sex.

JiJi456 · 27/04/2025 17:06

You think that science can't develop to match our advances in scientific research and understanding. It's wild that I reference legitimate scientific sources and the replies are just like "136 million intersexed people are just disordered and are actually outliers so it shouldn't impact the status quo of what I believe human biology should be"

If humans were clownfish we'd be swapping sexes all the time. It wouldn't be as "rare" as it is.

To put this 'intersex' to rest:

If there are truly people with mixed sex characteristics are there:
People who have a uterus that carried a baby to term that they fathered from the sperm from their own testicles?
People that are xy and got pregnant without donor eggs ( there is 1 known case ever who had mosaicism and had 1 xx ovary, only place they had xx in their whole body)
People who ejaculated eggs through their penis?
A third gamete?

I know the last two are silly but the first two show why sex is divided into two classes, even is the more severe disorders, the people have streaks not ovaries or testicles, are infertile and often need hormone replacement therapy to get the hormones their bodies need as biologically male or female.

Sex is not a spectrum. You cannot mix and match in the sexual development to get to a complete different category. You just get deviations in the pathways within the existing categories. So even DSD proves the binary.

Arguing differently is just plain silly by now.

GCITC · 27/04/2025 17:55

And to the OP, as the EHRC has laid out, any association of more than 25 people using sex as a protected characteristic to limit members, that sex has to be biological sex, and so they should not say this group is women only whilst including some males.

Any association that does not follow the guidance opens itself up to litigation, and therein lies the problem. It takes a lot of time, energy, courage and money to take these things to court.

Scientists reject a binary view of human sex at NIH symposium by Max Barnhart 2024

The Five Sexes: Why Male and Female are not Enough by Anne Fausto-Sterling 1993, revisited in 2000 (while it is written as somewhat satirical, Fausto-Sterling has reiterated her opposition for the sex binary).

The following is a news article in a psychology journal, but the writer is a renowned biologist and the sources in the article are amazing: https://www.psychologytoday.com/us/blog/governing-behavior/202006/our-biology-is-not-binary

Am I saying there's five sexes? No, I'm saying that sex isn't a binary system, but bimodal, where individuals can be on the two peaks or anywhere in between. The insistence in the medical field to keep the binary system actively harms intersex individuals and even those who aren't but don't fall on the 'peaks' of this system. I think keeping the 'female' 'male' labels are good but doctors need to look at more than just genitalia at birth, and at the very least 'intersex' should become a recognised marker for a birth certificate.

"People who have a uterus that carried a baby to term that they fathered from the sperm from their own testicles?" there have been no modern records of that, though there have been records of intersex people able to carry pregnancy to term with their own eggs and also have their own sperm, but haven't impregnated themselves because the baby would suffer from extreme inbreeding.

You can think it doesn't disprove the binary, I think it does. Regardless it doesn't negate the fact that medically we are in need of an overhaul and forcing intersex individuals to conform to one sex and not have an "intersex" marker for birth certificates is outdated leading to significant problems for them later in life. The fact that an intersex individual has to go through the same hoops as a trans person just to change their sex marker to a sex that equally applies is silly.
