Rainforests1, I also did not understand your post initially. Thank you for clarifying.
My answer is very politically-incorrect: some indigenous American peoples were racist. Or perhaps I should just say "very warlike"- they're not the same thing. As I understand it, the Americas were already populated by a large number of individual cultures when Europeans first made contact with them (I cannot say that Columbus, or any other Europeans, "discovered" the Americas, as the folks who first crossed the Bering land bridge from Asia beat the Europeans to it for I-don't-know-how-many millenia.)
Anyway, I don't think the question can be answered simply. I don't know enough about indigenous peoples of this area to answer it at all.
