I am a white nationalist. I can say that happily because I can also say that the term has been twisted and perverted.
First of all, I am white. No big deal, just sayin.
Second, I am a Nationalist, by which I mean I put America First above all other nations , peoples and their needs. I would stomp on another country’s neck if it boosted American power and quality of life. Its just another way of saying that I am an Ultra-Patriot.
Sadly, the liars in the fake news media have fused those terms together, sort of like you did, to infer that nationalists are some sort of racists or supremacists. That is a big fat lie.
