The funny part of this is that most people commenting there actually agreed with me; due to WWE's... inconsistent nature (sometimes it's very good, sometimes very, very bad), some fans of other promotions tend to look on WWE's fanbase with derision (the reverse is also true, by the way).

I think the problem is the fandom itself. One look at Youtube, Facebook and the like gives the same image: really strong opinions, refusal to accept other opinions, outright elitism/hate towards fans of different things, self-hate/hate towards new fans, wars between fans for really dumb reasons... that subreddit is actually more civil than other places I've seen (and the mods aren't as tyrannical as in other subreddits).
