Its so difficult to accurately convey complex thoughts on a chat forum, so apologies if my reply to this sounds a bit like an essay or clumsy (its late and I'm tired) but I will try to get across what I mean.
With the exception of breasts, all of the gender stereotypes in relation to women as not fixed. It is society that has decided which clothes, hair and makeup belong to women and which belong to men. It is used to negatively to control both sexes either through female oppression or toxic masculinity.
If anyone could wear whatever clothing or makeup they wanted without fear of ridicule, regardless of their sex, it would reduce the power of people who were doing it with negative intention.
I think there are a lot of men who like to wear womens clothes and makeup etc, who identify as trans because it is the only way that they can do so and be accepted (I'm not talking about the fetishists here who take stereotypes to extremes or trans men that demand to be let into single sex spaces - they can go jump!).
Although race, like gender, is a social construct, blackface is wholey different because skin colour is fixed.
We may share life experiences because of our femaleness, but the only experiences which we all share are uniquely biologically female experiences.
That doesn't track though - not every woman shares the same uniquely biological female experiences in the same way they don't share the same life experiences. That's why I said its a complex combination of everything all three elements - body, genetics and experience - because none of those things in isolation are common to every female.
Re: Semenya and Khalif. They were born with what appeared to be vaginas and raised as females.
I agree there may be some doubt in Semenya's case as to whether her parents and neighbours perceived her to be a boy even though they continued to nominally raise her as a girl and I am open to reconsider my position on her over time - but I'm not aware the same doubt round upbringing exists for Khalif?
Do you really think that a poor family in rural Sahara, where Khalif grew up, would have access to expensive genetic testing or medical scans, especially if there was no illness aside from a lack of periods?
Many people with 5-ARD who are diagnosed in their teens go on to live as males, but I see it as a perfectly valid life choice to continue to live as female for those that choose to.
You can't argue that XY alone makes someone male because you pull in people with DSDs like Swyers where they have a female phenotype, are generally raised female and don't have the benefit of testosterone at puberty that those with 5-ARD get.
As I've previously stated, I don't think that people with 5-ARD should be allowed to compete in women's sports - but if they have a largely female phenotype, have lived as girls / women since childhood and always believed themselves to be girls, then I am going to respect that as it is a completely different situation to men who don't have a DSD and absolutely no formative experience of being female deciding that they 'feel like a woman'.
Anyway - hopefully that makes some sense 🫤
