Earlier quoted context omitted.
I think it would be hard to make the label "ethnostate" stick to the US. It is too diverse.
it literally genocided the entire indigenous population, style 'red' in favor of another, styled 'white' while enslaving yet another styled 'black'
Yeah, but even in that characterisation it started with 1 ethnicity and the US replaced it with 2. So the result is less ethnostatic.
