Hate groups like that are not confined to the South. Anywhere there's people, anywhere they can spread fear, there they will be.
Even in my college days in ultra-liberal Noo Joisey, I occasionally saw flyers for the White Aryan Nation. Most of the time i dismissed them, thinking they wouldn't have enough backbone to show up anywhere. If they showed up on campus they'd be run out on a rail.
But just the fact people have hate like that in their hearts is disturbing.
