It's the fact that racism is ultimately stereotyping, which you could think of as rapidly gathering information under uncertainty. It's not very different than training an ML model. There's no way to capture all of the complexity of the world, but capturing some of it has immense survival value, and would have been the norm throughout the evolutionary history of animals (at least). We can be sad about the necessity of this, just as we are sad that most animals (and most of us) will die horribly. But it's an immutable fact of reality. If it were somehow possible to raise or breed a person that lacked any capability for racism or other forms of bigotry, they would go into the world like a sheep among a society of wolves. They'd die quite quickly. Better for us to simply acknowledge the truth, and try to rationally limit the fallout. Pretending it's not so simply makes things worse.
