In short, feminists from the 60's are starting to realize that no matter how much sociological, feminist propaganda they were fed in the 70's, the reality is that men don't want to date them anymore. And instead of accepting this reality and that their time has passed, they are becoming psychotic (your beloved Captain remembers quite starkly an episode where he was punched by a very left-leaning "feminist" after he told her he didn't want to sleep with her anymore)
Regardless, feminism is over simply because it failed in its sole promise;
To make women happy.
Enjoy the decline!
