My problem with Antifa, BLM, etc., isn't with the organizations themselves or what they stand for; it's the nagging suspicion (which history bears out) that quasi-COINTELPRO operations targeting them could very well mean that agents provocateurs of various stripes - including local, state, and federal law enforcement - might actually try something as cockamamie as derailing a train, in order to discredit those organizations. We've seen such things happen before: Operation Flex (www.thenation.com), The Newburgh Sting (www.npr.org), etc. ad infinitum. That one of these types of operations might get out-of-hand and lead to the deaths of innocent people isn't a stretch of the imagination. So I stay away from joining anything nowadays (former member of the Socialist Party USA - a Eugene V. Debs fan, don't you know).
