Fascists are far left-wing socialists. Antifa is a fascist group fighting the commumist left. Just like the NAZI’s in Geemany fought the communists for power.
No, they're fighting *for* the Communist Left. They Nazi Germany comparison isn't a perfect fit. Antifa is mostly a bunch of Socialists (the schools are doing a great job of indoctrinating them) aided by a sprinkling of Communist agitators (like the guy that led the outsiders causing trouble in New Orleans over the Confederate statues, they're all part of the same group). There are direct CPUSA and RevCom links.
They're stretching the term "fascist" to cover anyone who opposes their world view. Mostly that's Capitalists and Nationalists. Us.
