All groups with power eventually become supremacists, after enough time and cognitive reinforcement. The European "whites" were simply the ones who occupied center stage from about 1500-1950. They* controlled or wiped out the natives in all continents during that period.

Now, we simply have a different supremacist group wiping out the previous one, this time primarily by the pen rather than the sword, ranking peoples' moral value by supposed "intelligence" rather than race, conquering (and creating) power structures rather than land. Don't kid yourself that it will be confined to the West.

*Or rather, the subset of psycho/sociopathic, rich, intelligent, attractive, charismatic, politically connected, risk-prone, etc. among them, who led their lessers in all things physical and psychological. As occurs in all races, everywhere.
