i dont know if it's true that politicians condoned the rioting, ill give you people who arent politicians making the argument that riots shouldnt be condemned without fixing the issues that caused them, like mlk jr would say, maybe politicians who agreed with the overall movement quoted mlk too (?), but i dont remember politicians actually saying rioting was fine. charlottesville was an alt-right event that had counter protesters, the police organization for the event was botched so violence was almost inevitable. if i recall correctly it was the right wing that started the fight, not the counter protesters. i agree with that getting away from violence in politics would be good, i think antifa should abandon black bloc and stick to mutual aid and wearing normal clothes to protests.
