To be clear, the Han Chinese, the Japanese, and the Koreans all DO consider their own ethnic group to be superior to others, and they DO (culturally, if not by written law) tend to treat non-group-members as "lesser". A significant percentage of India still clings to their caste system. I don't know much about African tribalism, other than they keep killing each other for being in the wrong tribe. I'm betting that "we're better than them" is a part of that system as well.
And, to be honest, I wouldn't disagree with the "white nationalist" notion that our old system is better than the modern American mess in many (most?) ways, and reforming a new nation along those lines would likely be better. It has nothing to do with skin color, it has to do with Culture... and making a system where the other (imported and urban) cultures (and their habits and mores that have been dragging America down) are not allowed to abuse and ignore our system, and cannot impose their preferences on the nation, would likely make for a more pleasant, productive, respectful, law-abiding, polite, and free nation where people (of any skin tone) were not forced to subsidize the lifestyles of others.
Sadly, we are losing the Culture War, and badly... and we will not be allowed to peacefully reform our own nation within these borders... so here we are, forever stuck being told that the conservative movement is "really" about skin and not about culture and history and character and tradition... and we are apparently mostly unable to rebut the message in the public sphere.
(Note: Those minority/urban/imported cultures certainly have more than a few white adherents Again, skin color is irrelevant. It's culture and behavior that matter.)
Well said.
