What is this white nationalism bullsh*t?
They wore racist out, this is their replacement word. As a bonus this one can only apply to white people.
Why, this is the very latest MSM smear and all the proggie Cool Kids are parroting it! It works like this: a white nationalist used to be someone who believed in an exclusively white nation, just as a black nationalist does for black people. Ah, but we'll just change the terms a bit such that anyone who happens to be white and loves his or her country is now a white nationalist! And no, that doesn't apply to black nationalists...
White Supremacist is another rather cheap rhetorical neologism. The lefty defines the U.S. as an irredeemably white-dominated state and so anyone who believes in his or her country is therefore a white supremacist! Cute, huh? And that one works even if one doesn't happen to be white.
They'd never get away with this sort of ludicrous Newspeak if there were honest media to call them on it. There aren't. And so here we are.
