The stereotypical "Trekkie" of pop culture fame--a nerdy 40-year-old virgin living in his parents' basement--is like Bigfoot or the Loch Ness Monster. Maybe such creatures exist in reality, but I'm not sure I've ever met one.
Still, the stereotype has its origins in reality; before the explosion of occasionally negative media attention, I recall the ultra-geeks, the less than shapely fans squeezing into Kirk shirts or Uhura skirts, etc. Let's not talk about all of those bizarre, would-be Spocks
wearing giant rubber ears, and walking around with a pompous air, spouting Trek-isms like it applied to real life, and somehow separated themselves from the expectations of human relation (undoubtedly a defensive position).
So, some of the "Trekkie" stereotypes are grounded in truth, even while the people you describe:
Most of the Trekkies I know have kids, careers, and mortgages--just like everybody else.
