There must be some radio station or tv "news" station which continuously repeats this propaganda which tries to mix up the minds of their gullible listeners. It's the only explanation I can think of for why we are bombarded with topics like this one on an almost clockwork basis which attempt to conflate the right wing conservatives of the old Deep South with the modern day Democrats.
It's some sort of weird propaganda reinforcement technique we are seeing here. It's creepy in its robotic regularity.
Democrats opposed Civil Rights Act-meep! Democrats enacted Jim Crow-meep!
