Your quote from Dostoevsky is spot on. The problem for the progressives is not 1920. It is now. It is cognitive dissonance, the belief in things which conflict with observed reality. It is rejection, that is true, but not rejection by others. It is inner rejection. They turn their anger toward others in the hope that if they can make everyone disappear who disagrees with them, that their belief system will work. They cling to a failed belief system, and they are so completely vested in it that they would rather see the world destroyed than to reconsider their premises.
Well said.
The truth to Progressives is whatever they want it to be.
