Democrats trying to erase Democrat history.
Without realizing it, they are also promoting even more federal tyranny over the States. (Remember: The single most prominent issue of the Civil War was slavery, but there was a huge amount of animosity between the North and South that had nothing to do with slavery,
per se. It appears that our first Republican administration under our now beloved martyr Mr. Lincoln was disinterested in States' Rights in more ways than those centering on the knotty mess of slavery.)
Kudos are to be extended to the Yankees and the Republicans for stopping the abomination of slavery, but let's not pretend that the North did everything right in the run-up to the War.
