“...[T]he purpose of communist propaganda was not to persuade or convince, nor to inform, but to humiliate; and therefore, the less it corresponded to reality the better...” - Baron Bodissey
That full quote is on my FR profile page.
The effect described is the motivation for its cause.
The goal is to create this state in people, as they become highly manipulable.
Abortion is a good example. You force cognitive dissonance onto someone by having them commit that act. They become highly motivated to avoid reality and very malleable to those who support their dissonant state.
At some level, the creation of cognitive dissonance is a conscious act. The leadership of the “movement” knows what they are doing. I doubt that AOC knows. She is just a bartender.
Sounds like the theology of the Morning Joe & Mika sycophants...
