Well then it's not so out of the ordinary is it? Every fandom has the fangirls, the Rule34, the geeks who know everything about the game, the theorisers, the fanfic writers, the artists, the role players, the fans who love the game but don't interact with other fans, (that one tends to be me) the list goes on!
Regardless, you can't have a grudge against the fandom at the end of the day because we all have something in common.. we are just a collective amount of individuals who all love the same game.
No deal.
