Wow really? Because German Antifa isn't anywhere close to what you have described. Perhaps we Germans just breed better Anti-Nazi hate than you guys. Must be.
On a more serious note, Antifa, at least here in Germany, can hardly be using the same tactics as the Neo-Nazis and the Alt-Right, seeing as both march on the street spewing out their messaged and both, if given the chance, would clobber each other. There isn't much of a Variety. Though I suppose Antifa sends more of a relatable message than Neo-Nazis. As far as I can tell Antifa doesn't Hate Free speech, atleast not here, but I could be wrong I've only been to a handful of Demos where Antifa was present. No, I am pretty sure, atleast about the German branch of, Antifa is filled with Anarchists
