One way or the other, it doesn't make an iota of a difference for me where we originated. But people are differently motivated, and it's hard to second-guess their intent when it comes to these things.Yes. Given the amount of hyperscrutinization of the Out of Africa theory, and the relative paucity of such scrutinization on other origins of humanity, it's pretty safe to say that most of it comes from a place of supremacism.
Similar story with the Solutrean hypothesis. Or the out of India hypothesis, if you want to look at another region's supremacism.
