Players play like they want, there's no need to excuse what they do ingame as long as it's not against the rules. There are still lots of generalizations and jokes related them that will never wear off. It's part of our community's shared consciousness.
Pks are kids, pvp players are dumb, roleplayers are weirdos, alt-users have no friends or life, soloists are retarded, crafters are pussies, testers are carebears, polaks are trolls, russians are common enemies, french are idiots, gms are abusers, devs are lazy, the whole playersbase are assholes - according to nameless gm.
