Because people need to seperate and isolate themselves by groups. So we they can be better than another group of people. People need to be better than someone to elevate their own self worth. It's a video game. We can't see other people, or hear them on the forum. So we can't seperate ourselves by race, nationality or sex. So we are either Annoying PvE people or Nerf happy PvPers. And even within those, in pvp you are either a crybaby hunter, a crutch noob titan, or a...a.. a warlock? They're something derogatory. And then your either a filthy casual or stupid try hard in PvE. Which honestly, those classifications are just stupid. Putting down someone for just being causal and having fun is just as dumb as putting someone down for trying to do their best. It's racism, basically. It never goes away, it's a plague that even effects something that should be fun. Something that should help get away from that negative shit. But it's always there, cause we need to be better than something. It's almost just instinctive now.
