White supremacists get a lot of attention and make a great boogeyman. There's a bunch spread around all over the place and they pop out at protests and rallies and the like and the news loving a good controversy just goes and pours attention on them.

It's mostly a bunch of dumb fuck angry kids who want to play at their own kind of victim politics albeit one that has them being the victim of people not recognizing how superior they are or something. Since it's mostly a bunch of retards and there aren't that many of them the threat they pose is vastly overstated.

I'd say inflation is probably the number one problem in America at the moment. Well that and the general decrease in upward mobility due to various predatory practices that are geared towards the lower economic classes (payday loans for instance) but you can't make a boogeyman out of abstract economic issues.
