At the onset of the Civil War, only less than 1/3 of the inhabitants, of the Confederacy, were slave holders. Considering that the sons of very large slave holders were exempted from military service, the percentage, of those fighting and dying for the Confederacy, that had no a dog in the fight, was even greater.
In essence, most of the Rebs were fighting against their own interests, and, it was they that suffered most from the destruction that the war wreaked on the South. Therefore, in a sense, it was almost fitting that statues, honoring heroes of the Confederacy, losers all, be erected there.
If they had been a reminder of the Great Folly, that was the Civil War, they would have served a purpose. Their becoming, instead, objects of veneration, by the descendents of the people who were mislead, they served only as a reminder of the infinite capacity for folly, of our kind.
