I've seen plenty of slash fics that have bashed women as a whole (women = disease mongering sluts is usually the case, but controlling bitches also periodically comes into play). I generally try to avoid it (and I find it more avoidable in the Supernatural fandom as I've found that, for the most part, a very select few authors do it). I've also seen women who are very "Squee! Gay men!" (which... I have objectification issues with) do it in real life (ie I don't want to see those slutty women have sex, give me some men!). I'm not saying it's right or good; I'm merely saying it's incredibly pervasive.

I'm also not entirely sure how drinking on the job and having sex with a strange FBI agent on your desk makes a woman better than a stripper, morally speaking. (Really? Dean's the one who has trouble mixing up reality and porn?) I mean... I'm not saying that she should be bashed or anything, just that I'm not seeing the moral dividing line that the writer clearly did.
