I don’t think white supremacy/white racism is the result of an “evil spell.” As you acknowledge, this “position” has been ingrained within the majority of so-called “white” people from the very first moments they began to realize that it was they who constitute the world’s true minority. Writers and thinkers far deeper/heavier than I attribute the unrelenting greed, narcissism, worship of “rugged individualism” (capitalism), unrestrained nationalism exhibited by these people as defense mechanisms. They cannot “allow” people to freely interact because to do so means that at some point there will simply be no more “white” people.
