It starts by treating people with respect from higher tiers of the government. That justifies the voices of reason who would stand up for those who cannot themselves stand.

It also needs propaganda. Not modern propaganda, but actual propaganda.

Hence, "any movement or organization to propagate some practice or ideology" (1790). The modern political sense ("dissemination of information intended to promote a political point of view") dates from World War I, originally not pejorative or implying bias or deliberate deception. Meaning "material or information propagated to advance a cause, etc." is from 1929. Related: Propagandic. source

Propaganda exists whether intentional or not. It’s what drives culture, change, and resistance. It can be used to attack minorities. It can also be used to help minorities. In essence, propaganda is just a narrative which influences masses of people. At a different scale, you might call this a pep talk; large scale, it’s propaganda.

We could use propaganda which blasts some compassion into the minds of our countrymen.
