Who is actually rioting here? Police trying to sabotage the protests by making them seem more violent? There is some (disturbing) video evidence of that. "Young White Men"? Hollywood liberals urging "burn it down"? It would be helpful to have some numbers breaking down who is in the crowds (or supporting them). Nevertheless, everyone has gotta have an opinion so here we go:
Young White Men Abuse George Floyd Protests For Violence And Looting, Bernard from Moon of Alabama (right wing militia types)
The Minneapolis Putsch, C.J. Hopkins (Hollywood liberals and the "resistance" of disappointed Clintonites)
Coronavirus, Rioting, and the Privatization of Morality. Benjamin Studebaker (as long as we are fighting about whether it's seemly to riot we aren't challenging the system that has put pressurizing conditions in place)
The Federal Reserve's Coronavirus Crisis Actions, Explained (Part 7), Nathan Tankus (riots may actually be the only thing that makes Republicans and "austerity Democrats" in DC nervous -- see quotes from back in the 1970s).
