The assumption that the US is a 'white nation' and that anything but growing numbers of 'whites' in it is a 'Great Replacement' is working from a stand point that the US nation has an intrinsic skin color 'white' and intrinsic 'white majority' to begin with.
The fact is the US always has been and always will be a multi-ethnic nation that is supposed to be held together by a common culture, not a common race.
If one wants to be fair, the Naturalization Act of 1790 did limit naturalizations to free white persons of good character. But Yeah, I'm certainly a big tent nationalist for both the US and other countries. If you're non-white but want to embrace non-Woke US values, then you should probably be welcomed here.
