I've said before my line is at graves, and I still think the group doing this work for the military is justified, though maybe misinformed, or needlessly callus if they *will* go after graves.
The Confederacy will never be erased from history books, no one should fear anyone forgetting what they did, just because they are not glorified in public by the US anymore.
There is no pride in the Confederacy as a cause, no amount of soldiers honor changes the horrors that still occurred under ex-Confederates, and their 'Lost Cause' pushing descendants, towards their former slaves and others for generations till the Civil Rights era came around.
Edit: African American families and others who lost family and friends to the Klan or Confederacy certainly won't let history forget.
