Confederate statues in public places, like courthouses, are just this^^^^ They were erected to remind the black populace of who was in charge, and that the "rules" might be changing, but nothing was really going to change. We could have an awesome Confederate History Museum in Jackson if they were collected and placed there for historical educational purposes. Not one single person who passes one of these statues is being educated on history. They are being educated on what happens when hatred of fellow man is in power. If people are all about history, they can take the time to go research each removed statue and report back on who put it in place, when and why.
Putting a plaque in place is just as much of a farce as the 2 flag proposal.
