> Slavery, racism, and sexism have happened in every single human society that has ever existed in some form or another, the US isn't special here.

Sexism is different as its not a group trait that affects whole families or communities so the disadvantage is not inherited.

The US is not unique with regard to race, but not all societies are the same. The US has a history of race based slavery which had a cultural impact, and it had racist laws and lynch mobs etc. until very recently.

> have relatively little correlation with whether a particular ethnic group was acting racistly towards another one in any given time and place.

There were actual racist laws in the US which is pretty good evidence of people being racist in the 1960s: https://en.wikipedia.org/wiki/Racial_segregation_in_the_Unit...

In most of the world people could legally marry someone of different race. In the UK an author could depict a marriage between people of different races in a children's book in the 1950s - I cannot think of any American examples of the same.
