I'd say you have a very small, skewed sample if you've come to that conclusion. Some of the most narrowminded, bigoted, condescending, hateful, arrogant pricks I've ever seen are elitist gamers. Should I assume all gamers and fans of gaming are like that? Of course not.
I mean really, how long have you been here on ENW? Ever been to rpg.net or the WotC boards? You'll find plenty of examples of gamers harrassing other gamers just to make themselves feel better. Go find any edition war for example, or ask about sports, and see the hatred come pouring out. Oh wait, you don't have to
ask about sports, do you? On at least one board, one guy will come out and spit venom all over sports without any provocation.
But since you've flayed this dead horse to the bone already, and logic just doesn't seem to matter, you just keep on believing your own reality, you crazy, unique, special snowflake, you!
