Was the Civil War about slavery, or was it really about States' rights? The hundreds of thousands of soldiers that fought and died for the South never owned a slave. I think there's a lot more to it than just a handful (relatively) of wealthy plantation owners desiring to own another human being. They were fighting against centralized government rule from afar.
The former; don't delude yourself on this history revisionism people have been trying to push. As far as statues/monuments; completely inadequate if funded by government or installed in public spaces. You're asking black tax payers to celebrate a movement that saw to keep them as cattle, devoid of humanity or rights. The confederacy was a shameful part of American history that should be shunned whenever it comes up and anyone celebrating it called out as an idiot.
