I wonder how many groups like Antifa exist in the United States? Anarchists, communists and socialists fighting directly against the KKK, skin heads, Neo-Nazi's and White Supremacists who are misogynists, xenophobes, racists, bigots, and homophobes. Thank goodness those right wing groups have no propensity for violence, huh.
