Since it is leaderless some factions of Antifa are extreme left, some are what they say on the tin and are are anti fascist, and some are crypto-fascists who have appropriated the language of antifa as a smoke screen , this last group has most of the ones who go on social media and stir up ship , and bait people, and try to turn peaceful protests into riots to discredit the protestors…
The idea of socialism has a lot of appeal .
That is why wannabe tyrants latch onto it .
