These people are actual Nazis, waiving Nazi flags. We're not talking about people just saying "bush/Trump is a Nazi" crap (though Trump does find common cause with white supremacists, and was rightly castigated for drawing false equivalence between the nazis in Charlottesville and the counter protestors,one of whom was killed) we're talking about having actual, factual Nazis waiving swastikas around like they're going out of style. That's who antifa opposes.
