Presentism bullcrap.
What we today call racism was in that time the “settled science”. The Science of the Blood.
It was held as a scientific fact that there were hard coded differences between the races and that the “white race” was superior in every way.
Racism existed everywhere.
It didn’t need anyone to spread it.
The way they act ,it seems they all want to go back, to tribe and loin cloth mentality. 85% are animals.
