I don't believe the majority of men hate women, but for sure a minority do – and that minority is growing.
Somebody on a separate MN thread made a very good point. They were talking about the rise of single, childless women, who are happy on their own and don't want a partner. They pointed out that women don't need men as much as they used to. It's now OK to be single and childless, and to live on your own. You can earn your own money, buy your own house, go out drinking just for fun (and not to meet someone), etc. As a consequence, men must bring something to a relationship. Throughout most of human history, they didn't need to bring anything at all. They could bank on women needing them for money, security, social acceptance (to be unmarried was almost shameful), and so on.
The problem, of course, is that a lot of men have nothing to offer. They are oafish, boring, shallow, ignorant and miserable. And no woman wants them. Even as late as the 1980s, it was still shameful to be a single woman over 30. It was also shameful to be a single mum. So women put up with the most unbelievable shit from men – anything rather than be alone. That is changing – fast. And some men can't cope. A lot of them still expect single women over 35 to be desperate/grateful for their attention. It puzzles and enrages them that lots of women are now saying "nah, it's OK, don't want you, don't need you. I'm happy on my own. If I meet a lovely guy, who is kind and funny and interesting, then great, but if not, that's fine too."
Crap men can no longer bank on finding a woman, and it's making them furious. A woman on her own, with a career and friends, is not going to allow some moaning, farting, burping oaf, with zero conversation, to move in and wreck her life. And she sure as hell ain't going to look after him. Fifty years ago, she might have done, but not today.
