You’re entire criticism is based on “hysterical anti-nazis who start labeling everyone they disagree with as a ‘nazi’” or the notion of “left-wing authoritarianism.” No one is advocating either here. So what is your point?

If some people are behaving poorly (“from what we’re seeing from ‘antifa’”), then criticize them specifically, but that has nothing to do with what I’m talking about here or the movement as a whole.

You can always look at any group and find bad examples, but that doesn’t mean that the cause as a whole is somehow unjust or unworthy. There were bad actors in the Civil Rights Movement, the Abolitionist Movement, the Suffrage Movement, and Labor Rights Movement. Does than mean those causes were any less just? You’re basically saying, “If some people use this as an excuse to be assholes, then the whole thing is problematic.” I don’t buy that line of thinking, not for a second.
