I don't think the anti-geek attitude is as universal as you think. All through high school, I was the stuttering genius (I am pretty convinced that's how everyone saw me) who was terrible in gym and everyone loved me. I helped bring home academic challenge (quiz bowl) trophies and nobody ever picked on me. (I was class of 2002. Maybe it's generational?)

(I also had a younger brother who'd beat on people who might otherwise have picked on me. Nobody told me at the time, though. Whole situation was kinda weird.)
