even then those intersex people (born with both or either genitalia) are not the same as transgender (born as one sex, but identifies with another)
I was never arguing that. I was arguing that intersex people represent a deviation from the sex binary, which they do.
I'll try to make it simple although in this context simplicity is usually the argument of liars (like perpetrators of biological essentialism), the world is complex and this issue is complex regardless of who gets in their fee fees about it:
Saying: "All humans are born either male or female" is objectively false. Because it just is. If there are statistically significant anomalies then its objectively false. Not ALL humans are born male or female. And any point based on this objectively false statement is also false, such as that sex is strictly a binary.
Saying: "Most humans are born either male or female" is objectively true. Just as saying most humans are born with 2 legs is objectively true. Just not...when it isnt. So statements based on this are objectively true. But if we're going by biology, those arent the only 2 things even though for social function (as we defined it in the past) we shoehorned EVERYTHING into that binary, that doesnt make the binary fully valid.
If it did there would have been NO controversy surrounding Caster Semenya. Has vagina, legally a woman, is woman. But someone had a problem, and suddenly "no that was wrong, has chromosomal variation, has internal organs, is a man." Realitiy is, Caster is intersex and lived as a woman, which was fine until someone outside of Caster decided it wasnt. Feelings.
The essentialist says: "All humans are
supposed to have 2 legs." Which is a clever way of being able to otherize people who dont. I'm sure Hellen Keller would have had an interesting opinion on this take. All this does is socially normalize the majority. You have your 2 legs, so everything is ok. You're correct, by default. If you were born with one leg, something is
wrong. Something is incorrect. Think of a kid asking what's wrong with another kid born with 1 leg, or 0 legs. I dont think I'd like to portray that as wrong, a defect, like the parents f*cked up. But rather, different. Besides telling someone born with 0 legs that people are
supposed to have 2 means absolutely d*ck to them. And most of the disadvantages they face would just be because of how much having 2 legs is normalized, making access difficult for them. I mentioned Hellen Keller because she was a figure in American History who fought against this. Before her time there was almost NO accommodation for Americans with disabilities. They had to fight for recognition and validity against this exact same thought process, going from being invalid, to just people who are different.
