The KKK was not started, nor exclusive to Democrats. Yes, Dixiecrats were racist af. Yes, the Dem party, like all American parties, being predominantly led by white men has had to tackle institutional racism from within, and that work is far from over.
Since the 60’s, however, the Democrats have moved away from racism and toward inclusiveness while Republicans have embraced racism and fundamentalism to avoid facing a more liberal electorate. In the wake of W’s admin, the GOP did internal studies and discovered that they were hemorrhaging support among the growing minority segments of the electorate. Instead of adapting their policies away from the billionaire class toward more socially balanced priorities, they doubled down on voter suppression and white nationalism.
This propaganda bullshit doesn’t fool anyone with a functioning brain. But racist muppets gonna spew.
