I've been trying to get people to stop being rude to new IRCers for years.
People like Stabbity don't seem to realize that their offensive behaviour might not be simply dismissed by people who haven't been exposed to it for years.
I guess to them, it's just far more important that they be allowed to continue their stupid, immature little "d'hur-hur-hur"-inducing pranks than it is to make sure that new people on IRC feel welcomed and included.
