Understanding and updating beliefs on deeply engrained topics can take enormous efforts, but sometimes it can be so hard that the listener cannot even in principle accept the new reality. The listener is simply not ready, he lacks a vast background of reasoning leading to the new understanding.
What fact that you know is true but most people aren't ready to accept it?
By "you know is true" I really mean "you are very confident to be true".
Feel free to use a dummy account.
Most violence isn't.
AnyMost times an oppressive network in power exists - whether that's the neural network of a domestic abuser or a social network of a cult or an institutional network of a repressive state - the oppressed networks will reply with tit-for-tat (to varying degrees). When that network involves violence, violence will be in the tit-for-tat response. When that network involves ethnic aesthetic prejudice, there will be some ethnic aesthetic prejudice in the tit-for-tat. Defusing the problem requires deescalating and removing both ends of the thing, but also requires recognizing which sides of the network are producing more amplification of the conflict, because demanding the reflecting side deescalate first basically never works. Of course, peer conflicts also exist, but they're rarer than imbalanced conflicts.
