Looters are opportunists that have little to do with the reasons for any large gathering. The Macey's Parade, wins by a major sports team, even parades honoring troops can't seem to happen without criminals showing up to try and pilfer something or destroy something.
I don't think the looters have much to do with Proud Boys or Qanon, just as they don't have much to do with BLM. They are an extraneous variable, and it's a mistake to pair them with protestors/counter protestors.
Turning over and burning cop cars? That did happen, and while it didn't happen much, the people that were doing it belonged (I'm pretty certain) to the BLM movement, although I can't prove that. Singling out and beating/arresting peaceful protestors? Also didn't happen much, but it was an overreactive law enforcement contingent that did it, and I CAN prove that.
For the most part, protesting and counter-protesting has been peaceful. What I don't understand is how you and yours are still pissy about the outcome of the civil war, and that people like me can order from and eat at, the lunch counter. I don't understand the vitriol directed at protestors that are marching peacefully-- the moms in Portland, or the peacefully assembled people at St. Johns Church that Trump had tear-gassed.
There. You asked a serious question, and I gave you a serious answer and tried my best at my honest opinion. I'm sure the tens of people in here during the day will attempt to make me pay for that.
