What is the difference between “Trekkie” and “Trekker”?
It would be better if there weren’t one. In the early 70s “Trekkies” became a commonly known name for Star Trek fans. But when spoken out by detractors of the show, it gained a humiliating undertone, also because of the similarity of “Trekkie” with “junkie” or “groupie”. When someone, who does not know Star Trek, talks about the fans, “Trekkie” very often implicitly stands for the “Comic Book Guy” type – overweight men who are also computer nerds and have lost their grasp of reality. Therefore fans that don’t like to be called “Trekkies” any more refer to themselves as “Trekkers”. But I don’t mind if you call yourself or me a “Trekkie”.
