Feminists are often considered preachy and bossy, and you might go to some Reddit thread and hear incel, autistic types calling such women nasty names (sorry if I'm projecting a stereotype, lol). Anyway, though, I have met real wife beaters and it's no pleasant experience, for sure, so I can say there is a reason for the beliefs, just like there's a reason for anti-racist movements (It would be lynchings etc. duh.).
