America has been between 80% and 100% white and fairly homogenous for the vast majority of its history. It's only since 1970 that the demographics of the country were vastly changed.

Wow, this is seriously stupid. America had slaves back in the 1600s and earlier, and certainly as long as America was a country. You apparently don't think black slaves count as human beings. Wow. Never thought I'd see such a blatant display of outright racism and white supremacy as this on HN in 2023, but here we are.
You're also discounting the Native Americans, who were there all along and long before the white Europeans came.
