There are just 23 of them;
That's 23 males in a female only space. The number should be 0.
You could fit them all inside a classroom and have room to spare.
So what? Fit them in a men's prison, where they belong. Women's spaces are not for men.
Said previously, some people are born with the wrong body parts. Hermaphrodites are born with both. I've seen very effeminate males with more curvy bodies than females...while I haven't personally come across the opposite there is the case of Caster Semenya, more manly than many males.
Wow. Nobody is born with wrong body parts. Think about how offensive the 'born in the wrong body ' narrative might be for people born without legs, or with malformed kidneys - were they born in the right body? Hermaphrodites do not exist, every human who has ever existed is either male or female - a very few have DSDs, but each and every one is one of the only two sexes humans come in. And Caster Semenya is male, with XY chromosomes and a DSD called 5ARD, which only occurs in males. Sorry the BBC and world athletics lied to you, but CS isn't 'a woman with naturally high testosterone' , CS is a male, with ordinary testosterone produced by CS's testes.
Its never just a simple case of XX and XY, there is an outlier of people who are physically more in tune with the sex they were not born into. I grew up with one...he was as girly a girl could have been.
You seem a bit confused. XX and XY is very simple, and I've no idea what you mean by 'physically more in tune with the sex they were not born into'. Boys who like pink flouncy dresses are still boys, girls who like trains are still girls - it's just stereotypes. Any body can have any collection of interests or any personality, it's nothing to do with biology.
