"And how we burned in the camps later, thinking: What would things have been like if every Security operative, when he went out at night to make an arrest, had been uncertain whether he would return alive and had to say good-bye to his family? Or if, during periods of mass arrests, as for example in Leningrad, when they arrested a quarter of the entire city, people had not simply sat there in their lairs, paling with terror at every bang of the downstairs door and at every step on the staircase, but had understood they had nothing left to lose and had boldly set up in the downstairs hall an ambush of half a dozen people with axes, hammers, pokers, or whatever else was at hand? The Organs would very quickly have suffered a shortage of officers and transport and, notwithstanding all of Stalin’s thirst, the cursed machine would have ground to a halt! If... if... We didn’t love freedom enough." --Aleksandr Solzhenitsyn, Gulag Archipelago

We learn from history. These people don't get to terrorize our communities without pushback; no amount of finger-wagging will change this. (To be clear, I do not advocate violence, death threats, etc. But their little cosplay masks will not protect their anonymity. Let their friends and neighbors find out who they really are -- maybe they will feel shame for once.)
