Well that was........confusing. The shaky camera work didn't help. Everybody was dressed in black, they all looked similar in appearance, not much I could see to distinguish one side from the other - though did see a glimpse of a guy with a MAGA hat. And those techno tyranny asshats at Youtube restricted it.
I tell you one thing that we can be sure of, the guys who stopped the fight and got everyone to stop piling on the guys on the ground were right wingers.
Left wingers wouldn’t stop until someone was comatose or the police dragged them off.
