"The KKK was founded by Confederate soldiers, NOT the Democratic Party, as you imply. A small number of members were Democrats."
Well, that’s a nice twist but:
The Confederacy fought a war over what they thought was of the utmost importance, slavery. Slavery was not the paramount issue to the north. The south was led by pro-slavery Democrat politicians. The KKK supported Democrat candidates for POTUS in 1868. The Democratic Party didn’t start the KKK but evidence that its members were Dems is strong – a bit more than the “small numbers” you claim. Sorry.
