I agree, to an extent. Things that purely bash woman should be moderated. It's just wrong, sexist, and ignorant. But (obvious) jokes shouldn't. And most of the time, when VGC'ers are talking about woman, it's in a joking manner.
But I do agree that other things in the highlighted area in your post should be moderated a lot heavier. I've reported someone for bashing religion (on no ground) and the post didn't even get a warning.
All in all, Mods make mistakes. Everybody has those days. Everybody knows what, what I'm talkin' 'bout.... ~
