It's either genitals, chromosomes, or hormone levels depending on whom they're trying to harass and exclude.

A woman is anyone who believes she is a woman

A woman is anyone who JK Rowling believes is a woman

And racism. Don't forget the racism

According to chuds Algeria is both woke and backwards because of this.

lmfao this whole thing has me reading Caster Semenya's wikipedia article and:

On 16 July, she set a new national record for 800 metres of 1:55:33.[84][85] On 20 August, she won the gold medal in the women's 800 metres at the 2016 Summer Olympics in Rio with a time of 1:55.28.[86] The win reignited controversy over the rules on permissible testosterone levels; immediately after the race Lynsey Sharp, finishing sixth, broke into tears, having previously said that "everyone can see it's two separate races",[87] while fifth-placed Joanna Jóźwik stated "I feel like the silver medalist ... I'm glad I'm the first European, the second white", to finish the race.[88][89] Bioethicist Katrina Karkazis criticised the indignant response to Semenya's win as discriminatory.[89]

Trans Exclusionary Racist Fragility island

But she doesn't even have that, there is no chromosome test that has been done.

I recommend checking out Alice Domurat Dreger's Hermaphrodites and the Medical Invention of Sex, which is one of the earliest works in the anglo world exploring intersex from a social perspective, and digs historically into the process through which western medical fields developed an entirely arbitrary distinction to biologically "sex" men and women, and how that was propelled into dominant social ideology.

Despite her more recent anti-trans talking points, back in the day Dreger's work was a really big part of the developing intersex community (by community here I mean community as in, people beginning to "come out" as intersex or meet other intersex people and share their experiences and form an identity as intersex as opposed to the previously near-universal intersex experience of living in secret shame, believing you had an embarrassing and unique medical condition, or being left entirely in the dark as doctors performed surgeries on you and either never told your parents or your parents chose to bury it and lie to you).

It sounds like a significant part of the population everywhere has trouble with that

People can just read about things with an open mind. Definitely patronizing.

do they though?

Caster Semenya is from a large town in South Africa, Polokwane, the capital of its province. Population 130k

Definitely not "remote" by any stretch of the definition. Straight up racism by the author

They don't cause a broad chunk whoever buys what's written will take it for granted. Oh a person from third world, probably doesn't know how to read. It confirms what they believe so they publish it and some people will read it as "Yeah that makes sense"

I hope she takes home the gold

Today, ongoing as of an hour of this comment. She's up against a Hungarian boxer

works with trans athletes too. the transphobes don't want trans women competing with women, but I bet you they also don't want trans men competing with cis women. Do they want both trans men and trans women to compete against cis men? Do they want trans athletes banned entirely and unable to compete?

Jes, Poland, but apparently having the 'right' genitals is not enough; let's put it in vice versa, if you are a man, for example, and show as much testosterone and chromosome as a woman like her, the transphobes will consider you 'woman'...
