What I find amazing with this is that every few years we have to reintroduce this.
Anthropologists have known since the 1960's that the original Americans were black and genetically similar to Australian Aborigines. But science bows to political correctness and down plays this.
Since America was inhabited by Aborigines thousands of years before the Asians invaded, then the popular fiction of evil whites conquering peaceful victims fails. After all, the Asians who became the American Indians engaged in virtually complete genocide of the existing population. The Indians slaughtered the indigenous people and stole their land.
This is fact, but not politically advantageous. We want to cast the Europeans as devils with no redeeming qualities, but if the Indians were actually worse - which they were, then the moral outrage that fuels the hatred of whites, deflates.
