Antifa is a gift to the far right, to fascists and racists and all manner of white supremacists, who can point to antifa and say "They're worse than we are, they start all the fights." Well, we had many credible reports of the Charlotte white supremacy marchers hunting down peaceful counter-demonstrators as they walked home, and beating them up. Every action by those demonstrators, including speech, military style clothing, flak jackets and heavy armament, was threatening. 

Nevertheless the antifa anarchists are vandals who also assault people. They should be arrested for those crimes, tried and if convicted, punished to the limit of the law. Decent people of all political persuasion should speak out against all thuggish behavior no matter what the motivation.
