What's incredible is that they're blatantly in favor of male dominance (often white male) and will call pretty much any reporting on their opinions a "hit piece" even when all that's reported is the drivel they spout.
Feminists at least have some legitimate reasons to be upset, most anti-feminists are just huge pussies. You never see one and think "What a gentleman" or "What an upstanding representative of his gender", they tend to be pieces of shit.
Oh and besides, that's the price of patriarchy. The Man Rules of nature and masculinity mean that if some guy keeps whining about girls being tougher than him, that means he's a wimp and all the other guys can beat him up. If men aren't supposed to be good at something, that makes it girly stuff. Its like one of the Laws of Chivalry, dude. That makes them sissies by definition.
And in any case, when a bunch of women all hate some guy and are his enemies, it's almost always because of some shit the man did, so he totally deserves it.
