Tell me about it. Spend a decade a more spreading hatred about whites and men and now the left is surprised that some young white men respond to hatred with hate and violence.
On top of that, you have the "taboo" nature of white supremacist movements so the media coverage only makes them more attractive to that segment of the population that finds breaking taboos appealing.
"Some young white men", like those "very good people" in Charlottesville?
