That, plus the fact that they simply can’t get their brain around the idea that non-whites can be bigoted, too. They’re stuck in Mississippi, circa 1963.
In sad fact, the bigotry was often SOLD to these nonwhites, by lefties. Oh look at poor downtrodden you! Your great great grandparents were slaves, how could you possibly be free? And these nonwhites BELIEVE it. If they looked at even a SMATTERING of actual HISTORY... they would see that’s a colossal LIE!
GRRRRRR! I could proverbially WRING these lefties’ necks!!
