Antifa and BLM share a common core of beliefs in revolutionary Marxism. I'm not going to dig for resources that you won't read anyway.

To some degree, you are correct about Antifa as a reactionary organization. There is no question that they will go out of their way to counter protest to anything that they perceive as fascist.

On inauguration day, Antifa protested and rioted against our newly elected president in Portland, Seattle, Denver and California. I guess you could say that they were reacting to a fascist regime taking power. You could also say that they were reacting to the existence of statues that they didn't like and DHS agents in a federal courthouse.

As for the rest, I don't really give a shit about who gets bused in and for what. I do take issue with violent extremism regardless of ideology.
