These are ususally the groups that go out of their way to make it as difficult as possible to get around them. You either end up making a borderline-stupid pass of the entire group out of frustration, or you muscle your way through them little by little, and usually each step of the way they'll try to box you out. The HD dickhead reputation has been well-earned through years of douchbaggery, which is why there so much bashing here. There are about a million HD-centric forums for these guys to jerk each other off on, so maybe one of you disciples of the "Motor Company" can explain the appeal of hanging out here and whining about the anti-HD vibe.
