Peter David has a point (via Alex Knapp):

And all I could think of was how grotesquely unfair it is that science fiction and comics fans are tagged as nerds and dweebs and treated in a condescending manner when sports fans are just as "bad" if not "worse." I mean, where the hell does the media get off being snotty about fans who are dressed as Klingons when you can go to any Yankees game and see 1800 guys wearing jerseys that say "Jeter" on the back. The Klingon language may be incomprehensible, but no less so than watching two sports fanatics tossing around stats, names and abbreviations ("When he wasn't able to DH he was HBP and wound up on the DL when his ERA was 0.73, or else he would have been MVP.")

I'd go even further. Some of those sports fans go so far as to (gasp!) paint thier faces and bodies in the colors of their team. Man, that's geeky.
