To be honest we probably need a fourth. Just to make sure everything is covered.People who start a third goddamned rant thread.
Pet Peeves... hmmm... so many... how do you choose? People who stand in line for 10 minutes and then don't know what they want when it's their turn. People who piss all over the good things others are doing or act like them trying to help out their community is dumb or self-centered. People who think that you don't actually need to know anything about the religion you claim to be a part of (as Richard Dawkins said in one of the rare times we agreed on something, "Then why are you bother to pretend you are part of it??? And then he screamed and killed someone I think) or that a quick google search makes them an expert (that kind of goes for any subject I suppose).
