Maybe you should roll on a server that doesn't suck ass? Or maybe you think so highly of yourself that everyone outside of your group of friends appears to be an "asshole" or stupid? I don't have problems with most of the people I run into and can generally chat about whatever comes to mind.
To some extent, that's true. I'm fairly intolerant of people who don't apply critical thinking in the majority of their serious discussions. Almost everyone I've encountered that I haven't "befriended" is the type of person who fails to form a reasonable argument for even the simplest of issues. While I can cope with this sort of behavior in small amounts, it irks me to no end if it's frequent. I'm also fairly intolerant of consistent immaturity.
Hopefully you realize that both terms I mentioned are pretty relative. You probably wouldn't consider the average person on a PvP server an asshole if you either act like them or have a high tolerance for their behavior. I have the opposite of both properties, so I hope you can see why I consider people who run around doing /spit and /rofl to random people assholes.
