There's so much wrong with this post I don't even know where to begin.
"TERF" is a slur, and a pretty meaningless one to be honest. The people you label "TERFs" are not trans exclusionary, they're male exclusionary. They believe that feminism is for female people, including trans men and non binary people who are female, but not male people. This is feminism 101, just basic feminism, there's nothing at all radical about this idea.
The better term is gender critical, which means what it says on the tin: critical of gender.
The rise of androgyny through the glam rock/new romantic movement was inherently gender critical. Basically, "these boxes are regressive bullshit, men can wear lipstick and eyeliner and women can shave their heads if they want to, let people express themselves how they want".
That actually is progressive.
People like David Bowie challenged gender stereotypes and had fun with them. They didn't claim to be women.
The current generation of gender ideologues aren't challenging gender stereotypes at all, they are upholding and reinforcing them. They're not saying a man can wear lipstick, they're saying that if a man wears lipstick he is a woman because a woman is just a person who wears lipstick.
I have no idea how you can claim that is progressive with a straight face.
None of this has anything to do with challenging gender stereotypes, because guess what? Men and women can challenge gender stereotypes without men needing access to women's changing rooms, prisons and rape crisis groups and without being allowed to compete in women's sports.
And children can challenge gender stereotypes by wearing whatever clothes they like and playing with whatever toys and having whatever hobbies they want without needing puberty blockers and cross sex hormones and surgery to destroy their perfectly healthy bodies and future fertility.
Finally, if you think there is an argument against "natural born males", aka "males" in women's sports, guess what?
- You don't actually believe "natural born males" are really women, and
- That actually makes you a "TERF".
But if you think it's unfair for "natural born males" to compete in women's sports but fine for them to be housed in women's prisons and allowed to join women's rape crisis groups, you need to take a long hard look at yourself. Because caring about the sporting opportunities of young, attractive, privileged female athletes but not about the basic human rights of some of the most vulnerable women in our society is pretty grim really.
