Transgender man wins women's 100 yd and 400 yd freestyle races.

As the OP I have to say that is a leap that could win gold - sadly disqualified as being incorrect.

The winner - he has a name it's Iszac Henig - has yet to undergo ANY hormonal treatment therefore is currently 100% biologically female. Which is made clear in the OP but here is another article that also makes it clear:

As Henig has only, as he terms it, "socially" transitioned he would not be allowed to compete against men.

Whether or not his decision is avoid hormonally transitioning at this time because he fears he would get hammered if competing against men is the topic for another thread.

The point of this thread is that a transgender woman with a proven record was beaten by a 100% biologically female competitor.

And some comments about a bloke could or could not beat Katie Taylor, transgender women apparently have an advantage which means the death of women's sports (all women's sports it seems - gymnastics should be interesting). And the usual guff about "protecting women's spaces".

Women with naturally occurring testosterone don't count as women apparently even when that is the gender assigned to them at birth, and the one they identify as, they are dismissed as intersex - no-one has any idea how many men are intersex or have increased oestrogen levels and the natural advantage this can give in certain sports. It aids bone and muscle mass, rapid healing, and stamina. Oestrogen is described as a power hormone. Men aren't tested.

Much was made of Hubbard - a transgender women competing in the Olympics in weightlifting where some commentators here were convinced she would win (she didn't.) Ironically, no-one mentioned that a side effect of taking anabolic steroids - once the drug of choice for weightlifters -is an increase in oestrogen (to such an extent males using it can develop breasts). Hubbard was competing against people who have naturally occurring high levels of this power hormone which builds adolescent bodies designed to carry a developing fetus inside for 9 months and then endure the physical demands of labour - i.e strong, with a hell of a lot of stamina.

Zero consideration is given to the possibility that female hormones impart their own advantages, the existence of these hormones in biologically male bodies is not tested so their effect on athletic performance in elite male athletes is not monitored.

The narrative being put forward is that a male body is in every way superior to a female body when it comes to sports. All sports apparently. Even when that male body has has been taking 'female' hormones it retains this superiority. Therefore someone born biologically male will always beat someone born biologically female.

That is demonstrably not correct.

He identifies as male but as he hasn't begun hormonal transition is still biologically female according to the rules of the sport he is participating in.

To refer to him as her at this point is not respectful as he has made it clear he identifies as male and has had some, not performance influencing, surgical procedures.

Legal recognition of transitioning in the US varies from state to state but afaik it is rare that it as as relatively straight forward as Self ID in Ireland.

Henig has self ID'd - In Ireland he would be considered a man under our laws and his ability to compete in a women's race would be doubtful (I am not familiar with the laws regulating swimming here so I say doubtful rather than forbidden)

Do those men have naturally high levels of oestrogen? Are they inter-sex?

Oh wait - no one knows as men aren't tested.

They simply don't do gender tests on male athletes so there is no data. We do not know how many biologically male athletes conform to some hormonally an/or chromosomally based definition of "a man".

Man's birth cert says he is a man - ok say the organisers.

Woman's birth cert says she is a woman - well, we need to test you to be sure say the organisers.

I shared earlier when over 300 elite athletes were tested for a study and it found that over 16% of the men have low levels of testosterone that put them on a level with the 13+% of the females who tested high. Basically over 1 in 10 in both genders had similar, naturally recurring, levels of testosterone. But to compete only women are tested.

This has been the case since the 1936 Berlin Olympics.

Woke woke woke you say so often I, Not a Sir, am falling asleep with the utter predictability of your posts.

I said it is polite and respectful to refer to a person by their preferred pronouns all the time, not "just to their face" - which means calling them what they do not prefer "behind their back".

You imagined I said the rest.
