M'kay, scanned the article that was linked to in the dialogue underneath the comic. I think both Harris and Faraci have legit points...and both where they're acting like idiots. First, Harris; it is true, some of these ladies are just looking for attention because they like toying with people. Women like that are bitches because they're treating the men in a given fan community in a way very similar, if not identical, to the way some men treat women as nothing more than meat; both are using the opposite gender to get what they want with no concern for other people's feelings.
However, as Faraci points out, Harris goes so bonkers at points he overlooks the fact that anybody in costume at a convention is looking for attention. It's not fair to just blame the women who go there for it, the guys do it too. Maybe not for the exact same reasons, but it's still an attempt at getting people to stare. The question is whether or not the woman doing it would be appreciative of the people giving her that attention, or if she would just kick any attention-giver to the curb if he tried to get to know her better after she'd had her fun.
But while Faraci correctly points out that just because an attractive woman cosplays or shows up at a convention without a lot of knowledge of comics, movies, etc. the convention's about doesn't immediately mean they're doing something reprehensible, he THEN goes on to do something stupid; he talks about how nerds will overlook the "real" girl nerds and only talk to the attractive women that are "out of their league". Okay, the stupidity here is twofold. First, it insinuates that no "real" girl nerds can be physically attractive; nice job reinforcing the stereotype there. Saying that paints the picture of the nerd girl as always having to be plain looking or downright unattractive.
Second, by supporting the notion that person A can be out of person' B's league based solely on physical appearance, he also perpetuates the very shallowness he just tried to speak against. The concept of people being in leagues based on physical attractiveness utterly negates the idea that things like personality, shared interests, intellect, and the like are more important than looks. It's a concept that suggests no matter how much two people may have in common or may find appealing in one another, as long as one of them is better looking (by the majority-accepted definition of attractiveness) than the other, there can never be anything romantic between them.
