#Racism is (psychologically) cultivated paranoia and narcissism - by way of politics.
I.e "they're inferior" is #narcissism, or "they're coming to take our jobs" is #paranoia.
Then it's false pride, historical revisionism and delusions of grandeur, that leads to NPD.
The "us vs them" is literally the pack instinct being constantly triggered and trained to forgo rational thinking, leading to PPD.
Stir and blend, blend and stir, AND BAM: #racism.
