I have some thoughts on why feminism has become so widespread and entrenched. The preconditions for feminism's spread include our biological natures being that men take the care and protection of women and children seriously. Men tend to be very busy doing the things that keep our civilization going, so may not have time to delve deeply into the validity of complaints made by women. A big cause of the spread of feminism is that it was taken up as a useful tool for spreading communism and damaging institutions that communism wishes to destroy.

I'm glad you brought up the destruction of interest groups and hobbies. Notice how it was always women demanding access to something the guys were doing, playing golf at the club, for example. We never saw men pushing to get into a church ladies' auxiliary or some local Business Women's club (at least not until the trans invasion of women's restrooms, locker rooms, etc., but those guys are doing it under the claim the ARE women). I was a kid when this was going on, and I could never understand what the harm was for men to do something together.
