@asa The reason I bring it up is that America has always been a nation of immigrants but not really from all over for much of its history.

I put a lot of work into learning more about immigration and the USA and white supremacy etc. and came away understanding that the country was founded by people with very different ideas of what they were planning on building. So the USA has been both pro immigrant and anti immigrant in different ways its entire history, it hasn't ever been unambiguously one or the other.
