Racialism and its relatively recent variant, White nationalism, tends to reduce all political matters of importance down to whether or not a government is racially exclusive. The definition of ‘race’ also tends to be dumbed-down and diluted to the point to which it really is a social construct — a political fiction — rather than something with real genetic, cultural, and political salience.
Any racial group that defines Russians, Germans, Hungarians, Swedes, and Albanians as essentially the same people is missing an enormous amount of detail. It’s not even really the opposite of the one-worldism-race-is-a-social-construct vision of recent vintage liberalism.
It’s entirely possible that liberals will make a second reversal as dramatic and irrational as the previous reversal that began after 1945. It would be an unsurprising adaptation.
The other issue with this inclusive view of race is that it’s not exclusionary or discriminatory enough. It’s accepting far more diversity than is suitable for running any sort of stable society. In seeking a lowest common denominator, it shaves away critical distinctions among people. It would only be conceivable after generations of shallow, synthetic nationalism pushed by states worldwide. It only seems daring because it walks back the dominant ideology by one notch.
Attempting to create this sort of mirror image racial bloc just shifts crackers into the same barrel as the countless grabbing racial groups which all have academic * studies departments with grievances to monger. It’s pathetic, doomed to fail, and a path that runs directly to subordination.
