Yes it is. According to a recent article on Kotaku, anyway. Glad to see they are still upholding the grand internet tradition of getting offended on behalf of other people. The point of their rant seems to be that enemies like to call Catwoman a bitch a lot. And that's sexist. Maybe it's just the rampant misogynist in me talking here, but doesn't the fact that she is beating the ever-living shit out of these bad guys even the scales a bit?
I honestly think it was more a matter of the game's writers trying to come up with an insult to use that was mean without being truly offensive like whore or the c word that rhymes with stunt. So in the end, I guess the real problem here is that there just aren't enough gender specific insults for females. To remedy this, I propose we start making up more gender specific slurs just for women. Here's what I came up with so far:
Morette (female version of moron)
Dingess (females version of dingus)
Douchepurse (girl version of douchebag)
Shitskirt (woman version of shitshorts)
Fannyface (girl version of assface)
Muffmullet (girl version of dickhead)
