^This. I'm a Trekkie. I don't dress up in a Starfleet uniform in my spare time. I don't speak Klingon. And I like a lot of other things besides Star Trek and sci-fi. I don't buy into the notion that you need to call yourself a Trekker to somehow distance yourself from "those other super-obsessive, sad fans over there" (whoever they might be). Trekkie is a great and perfectly serviceable word. Why not reclaim it? As you say, everyone has their own level of 'devotion' to the wonderful creation that is Star Trek and silly distinctions like this are besides the point.
Anyway, I'm a Niner too!
