My biggest one:

These dudes spend SO MUCH time obsessing over how to have sex with women, and venting their anger about women who won't have sex with them. But then when it happens, they call her a slut, not worthy of any respect. The old virgin/whore thing.

I guess for a lot of these guys, they'd rather go back to an era when young women didn't put out (except in secret) and everyone knew the rules. Maybe a bit part of what's killing them is thinking that other guys are getting laid and they're not. Whatever the reason, they hate the women who give them what they so desperately want. Is it all about insecurity? i.e. they would never feel comfortable marrying a woman who 'gave it away too easily' because they would worry she'd cheat on them? Maybe it's that simple, but the hate for these women is what gets me.

I can sort of hear my 80 year old pre-feminist mom laughing over all this and saying 'dear, what did you expect? Men don't change.'
