Many years ago, I read that white men, and I assume white women, were afraid of the enhanced sexuality of people of color - mainly black & brown people. We demonize the things we are scared of, and this helps to support racism.
Racism exists worldwide, often hiding as religious prejudice, but it seems to be only a cover for racists.
As I have asked before, "If we white people are so superior, why are we so afraid of people of color?" To me, this is just a way of our hiding our insecurities.
Race is a social construct. There is only one race - the human race.
