If a pretty girl sat down at a table full of single, young male 'geeks,' so to speak, I'm pretty sure they would assume she's there more-or-less there out of pity.
This is kind of delicate. Because 99% of the time, I would bet the girl is simply geniuinely trying to be nice and friendly to people. But for the 'geeks,' I think it would be percieved as something different.
Much as I hate to say it...the stereotype is probably at least somewhat true. That male 'geeks' or 'nerds' or whatever are shy and awkward around girls and tend to be somewhat insecure in general. At least when they're younger.
Partly true? Seriously?
I was always horribly awkward around people as a kid, and I'm a woman. I was (and remain) very geeky. So you're saying that, by choosing to try to hang out with the geeks for no other reason than that I thought we shared interests (and they always pushed me away or were jerks to me, possibly because the whole female thing, and possibly because I was just as if not more awkward than they were) I was somehow making it all about me, all about wanting attention from them? And therefore, making it all about them...
No. I didn't want to be friends because I wanted attention from boys. There were oodles of more attractive boys in high school, some of whom I had crushes on and none of whom were interested in me (at least that I know of). And I can't objectively speak for my attractiveness levels, but on the whole I'd argue I'm one of the plainer people out there. No, I wanted to be friends. I didn't want to be treated like a princess, I just wanted to fit in with someone (guess what, years later I still don't). Most of the "geek girls," regardless of their subjective attractiveness levels, likely feel and felt the same way I did--just wanting somewhere to fit in, someone to talk to because we were horribly awkward, lonely people too, and yes, we thought dragons and video games and computers were awesome. But I, and I'm sure a lot of other women and girls, was pushed away. Maybe these "poor boys" were just feeling awkward about some random girl being interested in the same thing, or maybe they didn't want to share "their" domain with anything female. I don't know. I suspect that more harm was done to me by pushing me out of conversations and just generally having even the geeks be mean to me than has ever been done to them by having a girl or woman show interest in the same sorts of things they were interested in.
And, I'd also like to point out that these less-attractive (by whomever's standards) girls and women who hang out with geeks are somehow accepted as "more geeky," but they're also not at all the type of girl/woman the boy/man-geeks want to date. But if she's attractive enough that they'd consider dating her, she's suddenly not a real geek and only there for the attention. But oh, no, wait, if she's not attractive she's still there for the male attention. I'm with one of the previous posters: It's horribly egotistical to assume women only want to spend time with you for the attention. Believe it or not, men and women can be just friends, and people tend to gravitate toward other, like-minded people, to be their friends.
Sorry if that got too personal, but the "poor little geek boys being taken advantage of" thing is just... really old, and really false. There might be some people out there who'd do it, but by and large there are bigger and more delicious fish in the sea for those who have the appropriate bait, if fishing's their end goal.
