I'm actually a STAUNCH believer in the separation of races to preserve black people, black history, etc. in the long run and I hate the ideal of "one world, one race" or whatever.
But the logic presented in here (pretty much that everything comes from black people) kind of supports the ideal we should all be united, except under "black" leadership/following and not our present one.
The reason why you all's reasoning is errrrrr, is because there's no logical time period or DNA percentage that states when another race starts, and their connection to black history/blood/etc. ends.
If we are going to say that the Olmecs are indeed "black", well, when do they become the white genetic type that they are today? When do Europeans who supposedly came out of Africa, turn white? For you to answer those questions, you'd have to attribute the way climate and environments change features to such, but you all can't do that since you've been staunchly denying such happenings the whole thread.
You claim the Olmecs because of their nose, lips, and hair. But this kid looks nothing them and actually has more white features, but he is not genetically "white":
