Trekkies are fans.
Trekkers are people who are ashamed of star trek.
I'm not ashamed.
I most certainly am not ashamed of Star Trek, or the fact that I've been a fan for nearly 37 years. I call myself a Trekker because:
1. It's a more dignified
I absolutely do not want to ever be dignified.
2. A "trekker" is somebody who is actually doing something. A trekker is going somewhere, even if only in his/her own mind, conscience, or outlook on life. A trekker can be said to be an explorer, either in the outside world, or within his/her own consciousness.
Well I do post a lot..
