It's related to what we were discussing in the last thread: Being given a loser hand in the material reality. Those people were the past losers.
When we reached illuminism, and understood the natural laws and order of this world, there were clear winners and losers. Jews, blacks, gays, etc... were losers. The "correct" evident path was to phase them out and optimize humanity to thrive in this world.
But they didn't accept that and declared war against nature itself. They executed scientists who defended genetics en masse under communism, etc...
What used to be a battle for self-transformation and transcendence, became a battle against the natural order in a societal scale.

All of those perspectives are wrong, if you comprehend the dual nature of humans. But they are materialists, they think this is all there is to themselves and that they are legitimate inferior and need to find a way to not be genocided and win in the end. Their constant fear of genocide is because they think they should be genocided themselves, if they don't find a way around the laws of nature.
