People take a lot of their hobbies too seriously. I mean they are there for your enjoyment yet people are pissed off all the time.
Pissed off at a game, pissed off at a movie/tv show, pissed off at some band. Why do this to yourself.
Outside of sport teams I rarely get irate at any of my hobbies.
note: Yes I get mad at videogames when I'm frustrated at a level or something, but I don't go make 100 page thread about it. I get past the obstacle and move along.
note note: I loved the Dark Knight and saw it in IMAX twice. I don't care about declaring it the best movie ever or defending anything. Saw it, enjoyed it, it's all good.
