Watch in real time as Trans Reddit turns on one of it's own for suggesting that maybe they are biological men and arguing they are not makes them look unstable.

Depressing stuff, but it would all just be 'hasn't the internet thrown a light on some oddballs' if the oddballs hadn't somehow convinced the NHS and all the Royal Colleges and other professional bodies for HCPs, most businesses and charities and all the trades unions, the Civil Service, local councils, the Criminal Prosecution Service, the police, the judiciary, the prison service, the probation service, the teaching profession, the social work profession, both Houses of Parliament and virtually all the political parties in the UK.

PP's link relates to a case of mosaicism.

Yup, I see "gonad, 46,XY (92.9%), 45,X (5.9%), 46,XX (0.6%), 47,XXY (0.6%) (1000 nuclei)" for the mother and am thinking "0.6% 46,XX is enough 46,XX cells to make one oocyte" and one oocyte, ripened and released and meeting viable sperm, is enough to start a pregnancy.

This seems to be a case of 46XY CAIS with persistent Müllerian Duct Syndrome.

A tiny uterus is a uterus. Again, this mother had partial Mullerian duct development that, with some medical encouragement to finish developing, could do the job with an ovum donated by another woman. I take issue with the medically-inaccurate DM headline. That mother is not, and never was, a man.

That any of these cases are interesting enough to the medical community and the general public that they make medical journals and the lay press tells you that sex is a binary. If it wasn't, cases like these would be as commonplace as migraine sufferers and would receive no scientific nor lay press attention.

TRAs: "TERFs don't understand science."
The terves of Mumsnet: <discuss reproductive anatomy, developmental biology, and general relativity>

Also, you might claim that gravity doesn't exist, yet something is pulling me towards the centre of the earth.

Yeah, regretted that as soon as I pressed post😂

There was a thread somewhere on Reddit this week, I think in a psychology sub but am not sure, about how birds react very differently to women than to men. Oh my god the responses from people absolutely desperate to believe it's down to hairstyles and clothing colours and perfume use, because it cannot be that birds recognise sex. Time after time they were told these things were controlled for and they couldn't cope with the fact that birds can differentiate between the sexes in humans. It was delightful to see. It really bothers some people- they can't dismiss birds as terfs and evil bitch bigots after all!

Just for the archives of the ideology era

It's amazing how clownfish prove humans can change sex but not that humans can breathe underwater.

I heard in passing, (podcast, radio, one or the other) that there is research that show this is exactly what happens, people who use filters come to believe that they really look like their filtered self. But I can't reference it as it was just one of those things that sticks in your head.

I also heard in passing that when women are pregnant our blood thickens, our circulatory system is designed to deal with it but a male wouldn't be able to. Same again, I am no kind of biologist, but have been amused by the idea that all the squawking about womb implants is completely irrelevant in the face of the possibility of exploding.

The echo chamber is real and has real world effects

Terrifyingly so

I've just remembered: some years ago, when I was a regular on a certain science fiction forum, a trans identified male joined one of the general chat threads.

They were apparently Irish and had transitioned so successfully that they'd been taken for a real woman (they called it "cis", of course - first time I heard that word) and had been raped.

Over the next few weeks, they got loads of sympathy from other posters and spoke eloquently about their hardships.

One day, they posted a picture of themselves. No one actually said anything, presumably for fear of offending, but there was no mistaking that photograph of what was obviously a large, middle-aged man.

I'm a literal biochemist and people will still try to argue with me when I say medical transition changes biological sex.

I think this fella could get a literal Nobel prize if he could show how a cocktail of gender affirming hormones and some surgery magically changes small mobile gametes into large immobile gametes.

Yew trees. The Fortingall Yew has apparently recently sprouted a female branch.

I reckon when humans work out how to live to 5,000 years old, we might also be able to get the blokes to grow berries.

Half the speed of light in what medium?

It is like all the worst defence arguments in one place ! It is like an anti-science thread.

Luminiferous æther 😜

Blimey that is a depressing read.

Though to be fair I dare say the convinced flat earthers also put out word salad arguments back in the day, and managed to persuade the hard of thinking , though strangely enough none of them fell off the edge of the world , came back, and were therefore able to prove their theory to the satisfaction of the people who understood the science… there’s a lesson there somewhere.

I am a staunch feminist and strongly believe that no biological man should ever be allowed in women’s spaces, no matter how they dress/identify.
I do remember working in a country pub 40 years ago, as a barmaid.
A man came in dressed as a woman, I think this must have been a time when they had to dress as a woman for a year before they could transition.
Everyone in this village pub was sniggering at him, you can imagine how unusual this was back then.
I went to collect his glass, he was sat alone at the table, I exchanged a few pleasantries with him, and he looked absurdly thankful, frightened, but also resolute in his right to drink half a lager dressed as a woman.
I remember thinking how incredibly brave he was, to do that by himself, in a village pub where he may have felt safer, but was still ridiculed by everyone in there.
And I wonder, if he is still alive, what he would think about this generations attitude, where they think it’s possible to actually change your gender.
I would like to think that he would be bemused as the rest of us.

I don't. She hates all males despite not having met most of us. She's a bigot.

... but probably a very lovely bigot, and I've got a lot more sympathy for bigots since I discovered I'm one too.

It's the same with Physics. Newton's Laws of Motion aren't wrong. They are are extremely useful, but other factors come into play in some circumstances, for example Quantum Mechanics when we look at very small things.

And Maths. Arithmetic is used in every mathematical proof I've ever seen; it's not the whole of Maths by any means, but it's not invalidated by calculus, complex numbers, set theory or knot theory.

Someone, in reply to the woman being downvoted wrote:

If we’re not changing our sex, what the hell are we doing here?😂

Yes, well quite, what are you doing?

This ⬆️⬆️⬆️

THAT brought up some interesting visuals in my addled brain 😂

Biochemistry doesn't qualify him to comment on reproductive endocrinology or basic anatomy.

I knew of someone with a transitioning son who claims that their genes and chromosomes have changed as a result of puberty blockers and hormone treatment so that they are now genetically more female than male and will soon be indistinguishable biologically from a female.
