Only adding fuel to the fire of the argument that "white supremacists" claim white people are being bred out of existence but at the same time I've heard "black supremacists" claim that it's a plot to breed black people out of existence. The globalist powers certainly want all the commoners blended into some generic ambiguous brown, you also see it in some Sci-Fi settings like Subnautica where nearly every picture or in-game model of a human is some sort of mulatto.
