I think the stereotypical "Trekkie"--an obsessive, basement-dwelling virgin whose entire life revolves around Star Trek--is like Bigfoot. He may well exist, but I'm not sure I've ever encountered one in real life.
Most of the Trekkies I know have kids, mortgages, careers, and diverse other interests.
(Says the guy who has STAR TREK ornaments hanging our tree as I type this.)
Given how I got new STAR TREK ornaments every year, particularly ships, since they started doing that, my tree has more docked ships than Utopia Planetia.
