Uhhh, yeah, white nationalists generally see whites as inferior to everyone else.
Well, let me put it this way.
I'm "white". Big surprise.
I am all for preserving the traditions and culture I grew up in.
I don't want Sharia law, I don't like hip-hop/rap, and while I like food from a wide variety of cultures, I must note that lutefisk did not make the hit list, any more than tamales (too starchy for me), although I'd eat tamales before i ate lutefisk again.
That said, and being a straight, Christian, white male, I must observe there is a cultural war being waged against all four of those facets of my existence. Preserving my own culture and traditions is not claiming necessarily that they are the very best of everything, or that I should rule the world, just that I believe that, in a country whose legal and philosophical foundations were laid by people of my ilk, I would prefer to see those traditions upheld.
I don't want to enslave or own anyone, or force anyone to do things my way, but it's nice not being on the sh*t end of the cultural stick, either. The best way to have that is to have a country that upholds those values. That's one of the reasons Israel was formed, to do the same for the Jewish people, because they had suffered so much oppression elsewhere. I just don't want my culture to be subjected to the same depredations, hence believe in a justice system and Constitution founded on the basis of Western European philosophies, and Christian thought.
In a sense, because I believe the world would be poorer for the lack of that, I suppose I am a nationalist, and though my cultural ties to my genetics factor in, I an no racist, I just believe the results of that heritage, when implemented as intended, are superior to what other countries have and want to preserve that.
