These people are just friggin nuts
They live in an ideological bubble as tightly reinforced as that of Muslims. All the contrary opinions are evil, all their words are lies (fake news), horribly shamed for being a dissenting member and systematically driven to poverty and isolation, you’re shunned and denounced (though not yet killed) for leaving. They only hear media that agrees with them, their teachers tell them they are right and moral, and it is a sin to hear even contrary “hate facts”.
