After repetitive exposure to this propaganda (repetition priming), the people were beginning to believe and stand up for what each respective government had been flashing before their eyes, without them even knowing it.

The fact of being exposed to propaganda and misinformation, repeatedly and continuously, has a psychological affect over time.

The individual must not be allowed to recover, to collect himself, to remain untouched by propaganda during any relatively long period, for propaganda is not the touch of the magic wand. It is based on slow, constant impregnation. It creates convictions and compliance through imperceptible influences that are effective only by continuous repetition. It must create a complete environment for the individual, one from which he never emerges.

Propaganda, Jacques Ellul

Republican rhetoric follows Le Bon’s The Crowd method: Affirmation, Repetition and Contagion.

First they espouse an idea or belief (ex. Radical Left are violent animals). The crowd accepts these statements as true, regardless of reality.

Then blast it on repeat through every medium so it becomes internalized in their minds.

Finally, the contagion phase, where the crowd is spurned to action, whether it is getting out to vote, storming the capital or going door to door murdering “The Enemy Within.”

It’s not difficult to see what the fascist intent is behind the extreme violent rhetoric.
