It's worth nothing that...
1.) Some off those antifa accounts have a fair chance of actually being troll accounts, because antifa
isn't an organization. It's a decentralized movement that's purpose is to oppose fascism. Because it's decentralized, literally anyone can say they are antifa. This includes right-wing groups that use their symbolism and language to actually work against anti-fascist action.
2.) Antifa is not inherently violent. While antifa does believe that you need to oppose fascism by any means and don't dismiss the use of violence the vast majority of antifa only use violence (at least towards people) as a means of self-defense. That doesn't mean some people use violence far to readily but demonizing antifa because of those people is like demonizing BLM.
3.) The violence commited by antifa and violence committed by the far-right are not equivalent. This is not a defense of violence. I don't believe violence (at least against people) can serve as a means to the end, politically. But punching someone who chants racist bullshit or promotes the idea of a white ethnostate brought on by "peaceful" ethnic cleansing is not the same as beating someone because they are non-white.This sort of false equivalency is the same logic that the American government uses to send drones to bomb the shit out of Middle Eastern villages.
