I think the problem is more that some men are having to take a long, hard look at themselves, and they don't necessarily like what they see. Screwing that drunk chick at the party? That's not proving you're a man, that's rape! Slapping your date around because she won't put out after you bought dinner? That doesn't make you a stud, it makes you a thug!
They're being forced out of the back alleys and into the harsh light of reality. The big sports hero isn't being given a pass when he rapes the cheerleader anymore. The courts aren't defaulting to "She's a slut, so he's not guilty" anymore. The idea that men can't be held responsible if a woman dresses provocatively just isn't a good excuse anymore (if it ever was.) Men aren't being pushed out: they're just pissed that they have to let women in. Men are having to learn that the rest of the world doesn't revolve around whether they get laid tonight. And a lot of them don't like that.A sort of general feeling that women have gone too far and men are being pushed out.
