I'd recommend the Antifa Handbook by, I think Mark Bray (Bray like in jack@$$ sure fits), who is now a miracle academic. He was one of the first Occupy Wall Street organizers and that basically "made" him, being a spokescreature he then became an expert.
But these people are amazingly vacuous -- they're not "ignorant" but just amazingly stupid, skewed in their ability to use logic by an overriding sense of entitlement magic. Intellectually, if you can call it that, the mindset is still stuck in the mid-1930s European street fights during the Depression, Stalinist cadres versus the various fascist bunches. If only the Stalinists had won -- so they want to try again. Seriously. Borrow the book from your local commie community library, don't buy it. After you're done, you'll understand why you feel such utter contempt for them. And just a little pity when you contemplate their future lives.
