This is obviously to pander to White Supremacists, and so I'm against it like any red blooded American should be.
But for what it's worth, I don't have a lot of problems with memorials for confederate soldiers as I do memorials for confederate leaders, and this says it's a "memorial for the unknown confederate soldiers." If it's on private property in some middle of nowhere, whatever, I'll judge that person, but I don't think it's as egregious as a street being renamed "Jefferson Davis Parkway" or an elementary school being named "Robert E. Lee Public School."
Many civil war battlefields have monuments for soldiers who died during the Civil War, and those don't rankle me because the fact is most soldiers who died on the confederate side were poor, uneducated people who were conscripted into the army and had no choice. Even if they were filled with vim and vigor to fight for the cause of black slavery, it was because they were ignorant and destitute, and the people who were in power convinced them that keeping 'the negro as a slave' was the only way to maintain white dignity. The rich plantation owner's son didn't go to fight for Old Dominion and Dixie (and if they did they weren't at the front lines), the poor farmers son who had no choice did, and in that way, I don't reserve as much ire for the soldiers that died, versus the confederate leaders who sent them to die.
