It's funny white American racists think the country should be racially pure when really white Americans are the number one example of multiculturalism and open borders in perhaps all of human history. The idea of someone being part German, English, French and Irish historically was absurd given that Europe fought and killed each other for thousands of years. And even to this day other than in the US and maybe some other Anglo countries its pretty rare for a white person to be mixed.

But American whites 2019 are too stupid to realize this, they somehow think they are just "white American" and that was always a race or something.
