I would agree “white suprimist” suggests better than - not good.
However, “white nationalist” says a white person who puts America first - a patriot - that’s good, mighty good.
Then why not just "nationalist"?
Hey I have a little secret for you. Not all Americans are white.
Once again, I don’t know what it is exactly, that Rep. King said.
From the article, I know what it is that somebody else says that somebody else says he said.
What did Rep. King say?
One can be a Nationalist, and one can be White. That makes one a White Nationalist. Correct.
That’s not the same thing as a “White Nationalist”, believe it or not. Let’s hear what Rep. King said.
USUALLY, when someone is branded a “Black Nationalist” or “White Nationalist” it refers to a very militant, specific type of racist or racial supremacist seeking to carve out a segregated society and the rest of it.
