the mistake people make when talking about prejudice and fascism is that there is some fixed table of which group oppresses which other group. The use of predator-prey as a metaphor probably reinforces this mistake. because it's not as though white people evolved to enslave black people. The reason that happened was because a few enterprising southern Europeans figured out they could buy slaved from Africa, put them to work in America, sell the fruits of their exploitation back to Europe, use that money to buy more slaves, and triangle their way to riches. Everything about the USA, from its massive riches to its shitty race relations, is a testament to just how many multi-century-long fortunes were built on that.
But it's not a force of nature; it's a grand historical accident, like everything that happens between humans.
