Now in the interests of fairness, we have to give points to the ancient Egyptians and inhabitants of the Fertile Crescent for a lot of early art and agriculture. We also have to give credit to the peoples of India, China and Japan for more early aesthetic and other contributions (the Chinese came up with noodles, gunpowder and paper, for example). But the only significant contributions in the last five hundred years have been from Western Europeans and their offshoots. Sorry, but there it is.
Unfortunately the most recent developments in Western Civilization seem to be designed to tear it all down and apologize for coming up with it in the first place! To any person of normal understanding and moderate knowledge of history this seems quite insane.
But go read the article and see if you find the argument convincing. Just one caveat: the citing of statistics is, by itself, not an argument. Quotas and Quality are contradictory notions.
I am, of course, sorry if I have offended anyone, but frankly, I find statements like "Western Classical music is Rooted in White Supremacy" to be deeply offensive!
