You know, I'm a nerd, and damn proud of it. I certainly talk about it enough, as you well know. But I can't say I disagree with this guy, even if I don't frequent a lot of the geekiest places on the Internet that go in for Nerd Nationalism. There comes a point on the nerd continuum where "passionate fan" becomes "asshole obsessive." It all boils down to an essential truism life lesson: don't be an asshole. People don't like assholes. It's not unique to nerds or sports fans or anyone else, but it's true for all of them.
So shut up about Batman once in a while, and stop it with the zombies. Please, stop it with the zombies.
