LOL! Many thanks to you, and to the others who have endeavored to enlighten me ;-)
Oh but wait...there's more!
One of the oldest tricks in the RAT playbook is to blame the opposition for that which you yourself are doing. Then if you get caught you can say, "well everybody does it".
They have been playing the race card on the Republicans for decades even while they were still suppressing blacks including "The Great Society". Now they seem to be afraid that the voters (or maybe just black voters) will learn the truth.
If anyone has a reason for "white guilt"....it's the RATs.
Real history has been purged from the democRAT schools, except for "black history" indoctrination. They implemented affirmative action, black on black crime goes unreported, and America's second black President could do no wrong. etc etc etc
As you likely know, the Republicans have their annual Lincoln Day Dinners, and it used to be that the RATs had their Jefferson/Jackson Dinners, but now they have finally jettisoned the two former slave-owner figureheads.
I'm sure they bristle at being reminded of their darling "Conscience of the Senate"...the late Great Grand Dragon of the KKK, the "honorable" Robert Byrd.
I don't know if this is the actual motivating factor, but I am guessing that; with the voter fraud investigations, the mass exodus of wetback voters, and Trump directly addressing the blacks "what have you got to lose" and the ever diminishing RAT numbers in Congress and state legislatures...to keep from going extinct, they have to pull out all the stops....and that is what we are seeing here.
"Russia, Russia, Russia" is faltering, they can't really defend the DC gravy train, terrorism, Hillary, Obamacare, and illegal aliens, so all they can do is declare Trump and his supporters to be White Nationalist Racists.
They'll do anything to hang onto power, even if that entails generating a real deadly riot, with actual violent left wing radicals, and Fake "right-wing" racists.
