Nope, it's just that Democrat propaganda works so well that you guys managed to convince even some KKK members that they're on our side, which they're not. After all, it was the Democrats who were in favor of slavery, it was the Democrats who murdered Lincoln after they lost the civil war and took power afterwards, it was the Democrats who opposed black citizenship and their right to vote, it was the Democrats who made the KKK to terrorize the black community as the Democrats' military force in much the same way the SS did in Nazi Germany, and it was the Democrats who made and enforced segregation.
It was only when EVERYTHING they threw against the black community failed because of Republican interference did they go "Hey, if they get to vote, might as well convince them to vote for us!". In fact, President Lyndon Johnson was said to have said "I'll have them n*****s voting Democrat for 200 years."
Even now they're hurting the black community with failed welfare programs, opposition to school choice to keep them trapped in failing schools, and language police ending any kind discussion while leaving the blacks vulnerable against violent crime.
Do you honestly think that the party that's fought for the blacks for so long would endorse the KKK? And do you honestly think that the party that's been against the blacks until they had nothing to fight with could be trusted?
