To add to this, your ordinary male hormones permanently change the body over time even if you aren't working out. That is why it gets progressively harder for transwomen to pass based on when they decided to transition. The way your muscles and body develop can't be undone because you started taking estrogen and got castrated, that's just not how human biology works and every honest person is already aware of it.Well, looked at a certain way, everything in nature is a spectrum. But what the people pushing this interpretation ignore is that it doesn't matter. Suppose we invented the perfect society where all of our social institutions are minutely calibrated to your position on the infinitely gradated sex spectrum. The right bathroom for everyone, the right sports league, the right pronouns in the language, everything.
Even then, you'd still have people at point A on the sex spectrum who have a fetish for being treated like point B. You'd still have the strong (however defined) who long to run with the weak. And we'd have the people whose fetish is simply browbeating well-meaning society into tying itself in knots for them.
Which is to say: troons will always be with us.
To be fair, radical feminism isn't really connected to postmodernism or deconstructionism per se. You can hold feminist views and being a postmodernist, but the postmodern thinkers didn't write about feminism or think about it as anything but an afterthought, if that. I'd say TERFs are more influenced by traditional forms of Marxism and see gender as a form of class.Consider that TERFs are a reactionary group that could only exist within a society that permits men to call themselves women. There is no definition for sex/gender beyond biology, which is why "trans" is necessary, but Post-Modernists have thrown away the biology textbooks and replaced them with fantasy novels about how pretending you are x means you are x even if every cell in your body, even your hair, has a y in it. If modern feminists don't like trannies moving in on their "terf", maybe they shouldn't have made up nonsense rules about gender to try unsuccessfully to revise biological reality.
