Now that is interesting. It’s funny that the prevailing myth up here is that Klan people are right wing extremists. Obviously not the case.
The Democratic Party is more complicated than most people realize. And the whole left/right paradigm is not as useful a tool as people think.
Just remember. The Democratic Party was the party that backed slavery, and Jim Crow race repression right up into the modern era. They were the lynch mobs, and the guys with the firehoses going after the blacks; they were the klan night-riders burning down churches and killing people right up into the modern era.
The Repubs were born as the abolition party, and opposed Jim Crow all during the bad old days. During most of history, they were the only party that would accept black membership, which is why the klan was necessary to repress black political activity. The Repubs were the ones who finally broke down the door on Jim Crow; it was the Democratic Party that finally changed their position on the subject.
They’ve tried to re-write history since then. You can’t blame them.
