Point taken.
One more point about those decrying the removal of statues of Confederate "heroes" is that the vast majority of those erected throughout the South and other places were funded by groups loosely, if not directly, connected to the KKK or Sons and Daughters of the Confederacy.
There has never been, in my knowledge, a monument removed from a battlefield.
Just an aside, there was a recent article in the Washington Post about the Lee Statue in Richmond that was removed. It has been melted down. Evidently the bronze was highly contaminated.
