Can you just let people have their fun? How can someones name really piss you off that much?

I mean shoot, there was a thread on these forums with funny names. And you want to make someone else change theirs? I don't like your name Knighthill. You have two words in your last name and it is really innapropriate.... really now, just let people play. You know damn well it is making other people laugh. Geeez a thread about this.
