Also, I think OJ (if it is he) is completely wrong about the generational point. The assumption he makes is that younger people are more tolerant, liberal-minded etc than the older generation, and that when the oldies die out the new order will take over, just as happened with attitudes towards homosexuality and other issues of sexual morality.
A couple of reasons why I think he's wrong. One is that, to use Gloria Steinem's words, women become more radical with age. Once young girls start to experience the full horror of what it means to allow men into changing rooms etc, they will change their minds.
Another is that in a couple of years, I think we'll see a wave of lawsuits from detransitioners, which will probably put a brake on medical transition and bring to public awareness the reality of what transition involves.
The third is that not every attempt to make sex laws more liberal is successful. The most notable example is the way that PIE latched onto the campaign for homosexual rights in the 70s. It seems to me that since then we have become far more intolerant of older people having sexual relations with young people. There is a huge moral repugnance at paedophilia, but also of older men going after 15 year olds. When I was young, the idea of older men being attracted to schoolgirls was considered quite normal and a topic for humour. Not now. So in OJ's place I wouldn't assume that trans ideology is going down an inevitable path towards universal acceptance.
