Yeah, I agree, it's a learned trait, but I guess I sort of misspoke.
I think people can learn racism from media, but I don't think that X event can turn someone into a racist.
I think it just takes latent traits and previously held bigotries and exposes them.
It's like when people say that shitty things BLM protesters have done has turned them into a racist, which is a ridiculous premise.
Nothing could "turn" me into a racist, because I am not a racist.
