>No where else in the world has the massive amount of diversity that the US does at the scale of the US. It’s not even close anywhere else so it is difficult for both US residents and people of other countries to fully comprehend.

I honestly feel as though this is a lack of awareness of other regions and the differences inside of them. I don't know how you can make sweeping statements like that. A cursory look at a linguistic diversity map should immediately hint at a different reality, and that's just one metric. There are places in Africa where you have genetic lines that are distant by tends of thousands of years from surrounding villages as measured by their Y chromosomes.
