Yeah, they do that. Watch a live feed showing the evening of the last Patriots' march in DC. This was after the Patriots went home or to their hotel rooms. It was the Proud Boys. They came on the streets to save the day. They went looking for antifa. Chanted foul language, especially the women. Staged a fight.
Then got back to the Harrington Hotel (someone booked the whole hotel for them) and the Proud Boy Leader gave a talk. It's time to drink BEER he said. He was on a couple foot raised patio with a hedge. At the end he stepped through the hedge and onto the sidewalk. A spectator in the front row took off his Trump sweatshirt and proudly showed off his Biden tee shirt. antifa/blm/proud boys/boogaloo? They all the same. They all get paid by the same backers.
