India and Communist China have been proven beyond a doubt to be the two most racist, xenophobic societies on the planet.
Roddenberry was already onto something in the late ‘60s with “Space Seed”

America's "sins" of African slavery, color bars, Jim Crow Law, Asian immigration prohibition, etc. are all now in our distant past. But they are a useful a bludgeon for the Democrats (the direct descendants of the principal practitioners of said sins) to use in garnering the votes the gullible grandsons and granddaughters of their ancestors' victims. It's infuriating.
