Is there such a thing as White Supremacy?

 I would say not.

The people who could be superficially classified as White Supremacists admire non-Whites for their sticking-togetherness.  These so-called White Supremacists then exclaim:  “What is wrong with white people?!?”  If anything they want a white race consciousness akin to the race consciousness of the blacks.

And if someone was really a white supremacist, he would have to think that Joe Biden is the greatest thing since the invention of the internal combustion engine.  White supremacy does not exist because it would be internally inconsistent if it did.
