People can always be convinced to turn on one another. All you have to do is convince them that their way of life is being attacked. Denounce all the pacifist liberal bleeding hearts and feel-good heretics, the social outcasts, the educated. Call them elites and snobs. Say they’re out of touch with real patriots. Call these rabble-rousers terrorists. Say their very existence weakens the state. In the end, the government need not do anything to silence dissent. Their neighbors will do it for them.
