The Nazi’s looked at US segregation laws to figure out how to remove civil rights from certain groups. Hitler bad, but at that period of time talking to a white woman was a lynching for a black man in Amurica.
That didn’t stop until 1981.
But I had a black student refuse to drive in a car to a retreat in NC because the other occupants were white girls. That was 2000. That was the camel’s back moment that told me it was time to leave the USA.
