How? I have a theory.
It was bad enough for white southerners to be forced to acknowledge that without the “dark-skinned foreigners”, the south collapsed quickly economically. (As soon as they had to do the work themselves.)
And then they found themselves also forced to admit that another “dark-skinned supposed-foreigner” brought America back from the brink republicans under “W” pushed it to.
They’re tired of having to admit to being losers, indebted to those they hate. If they are inferior to “them”, what’s left for them to be? (Haters, is the answer, trying to reverse it all at ANY cost to humanity….including themselves.)
