Earlier quoted context omitted.
The world is less racist now than it was in the past. What mechanism do you posit for this?
I can't reply to the sibling comment that suggests education, but a corollary to education is that many of the people who had deeply-engrained racist beliefs are dying/dead from old age. I agree that the world is less racist now than it was in, say, the 1950s, but my personal experiences with the elderly suggests that the people who were racist in the 50s and are still alive are just as racist now as ever.
Don't you see the contradiction here? It can't be both.
