@idea_enjoyer I think most of this is the internet's infinite support group problem. Everyone can surround themselves with what seems like a massive amount of people who will encourage them in this cultist support group of good vibes and positive affirmation.
Then you have a culture which doesn't want to be seen talking back to or down to women and whatever inane shit comes out of them is unarguable because, well, if you do you hate women. So you're selling women liberation from the pressure of femininity and their own preconceived mental ideal of femininity (which is based on weird, outmoded 1950s caricatures or high school pretty girl drama). And that liberation feels freeing. Scary at first. Bad haircuts and flannel. Then that seems to work with enough friendly backpatting on Discord and in Telegram and WhatsApp groups. So on it goes. Most stay casual, but some get themselves worked into a frenzy and the cult celebrity goaders convince them this is what they always wanted. True happiness is just a tit chop away. You'll be free of all that pressure and a poster-them for the cause to boot!
No risk to your social standing either, which women are genetically incentivized to avoid at all costs. In fact, it makes you bulletproof! Win-win-win! But five or ten years from now, when the support group is gone and the fiery fervor for sticking it society has dulled, she'll probably kill herself. It's a real tragedy, like you said.
