Racism was seen as a form of social Darwinism
Social Darwinism believes in the premise of the existence of societies superior to others.
In this condition, those who excel physically and intellectually must and eventually become the rulers.

Thus, they would go extinct following the principle of natural selection of the Theory of Evolution.
