There are around a billion women stuck at home in horribly patriarchal third world countries, who often don't even dare going outside because either their family forbids it or going outside is plain dangerous and gets you instant harassed.
They spend all day online, learning English through a combination of school and kpop/anime/games/shows and get extremely radicalised; the experience of seeing the women portrayed in that media as often free, independent, beautiful etc creates unimaginable rage against men in them, because life COULD be so much better. It then gets sublimated into these 24/7 viral shitposts.
It's going to nuke fertility harder than even the most hitlerian sterilisation program you can think of.
A man refusing condoms is "a preference" but a women refusing pregnancy is "murder".
That isn't morality, it's misogyny.
