Naming one or two obscure right wing internet hate sites isn't going to convince anyone.
It's not just "one or two obscure right wing internet sites"
There is just as much hatred and calls for violence on the right as there is on the left.
Pretending one side is worse than the other just exacerbates the problem.
Just take a look at the people here that call for violence...and the others that cheer them on...to see what I'm talking about.
