Block lists
Regressive leftists have "block lists". They literally BELIEVE it when they are told, "You should never listen to these people."
How is that any different than having a list of heretical books that you are not allowed to read?
BTW, if you BELIEVE people who say "Don't listen to these people." you are fucking pathetic, weak, stupid, obedient and inferior.
That's the Antifa Shinobi Psycho System for ya.
