I see you're in here propogating the same dishonest material that the right wing has for a while. Antifa is not a leftist group, hasn't ever been, that's a right wing us-vs-them talking point. If Democrats were to take a fascist approach to governing, it's assumed antifa would fight them as well. It just so happens in recent years that the right wing in our country has embraced fascists. I'll admit, this propoganda has been very effective.
I've linked spronsen's supposed manifesto below.(found via Reddit and imgur) Reading it, he sounds like your type of guy. Especially your deep concern about playing semantic games (ironically, you're typically the one playing the game)
He's a professed Anti-fascist (antifa as we know them), and anarchist. He doesn't appear to be a leftist in any form, but hey....dont let that stop your increasingly dishonest posts.
My personal opinion, glad nobody was injured. I can support protests, but violence like this is not good and I won't support it.
Furthermore, reading his manifesto, if we can really even call it that, he would not agree with an independent of a centrist mindset like me at all.
Maybe though, the burn it down crowd can relate, even though this guy said we don't have to.
