here is what you have difficulty understanding:
It was DEMOCRATS who created the KKK in the 1866.
“Founded in 1866, the Ku Klux Klan (KKK) extended into almost every southern state by 1870 and became a vehicle for white southern resistance to the Republican Party’s Reconstruction-era policies aimed at establishing political and economic equality for blacks. Its members waged an underground campaign of intimidation and violence directed at white and black Republican leaders.”
It was DEMOCRATS who created Jim Crow Laws.
“Jim Crow laws were state and local laws that enforced racial segregation in the Southern United States. Enacted by white Democratic-dominated state legislatures in the late 19th century after the Reconstruction period, these laws continued to be enforced until 1965”
It was DEMOCRATS who opposed black freedom,
Before Charlottesville, Democrats voted for racist policies for more than 100 years
"Over the last 100 years, Republicans have stood up for African Americans while Democrats not only stood on the sidelines, but in fact served as obstructionists to civil liberties Here are at least 12 examples in which Democrats voted against African Americans, and Republicans voted to free them:
Democrats voted against every piece of civil rights legislation in Congress from 1866 to 1966 – a whopping 100 years. That is a dismal record for today’s Democrats who would like you to believe that history has been on their side on this issue.
Democrats voted to keep Africans Americans in slavery, opposing the 13th Amendment which officially freed the slaves. Only four Democrats voted for it.
Republicans also passed the 14th Amendment which granted slaves U.S. citizenship; Democrats voted against it.
Republicans also passed the 15th Amendment which gave slaves the right to vote. Not a single one of the 56 Democrats in Congress voted for it."
Shall I have to post a full list of voting records, to show that it was the Democrats who chronically opposed black freedom?
