The Confederate States of America declared themselves an independent nation based on a slave economy, attacked American soldiers stationed at Fort Sumter, and waged four years of war against American soldiers serving under the stars and stripes of our great nation
Yes, the Confereracy was an enemy nation, and neither the CSA nor enemy combatants who served in their army should serve as namesakes of our public property or public commons.
There are millions of acres of private property in the South if Neoconfederates want to have shrines to the nation or army of the CSA.
The 1859 song "Dixie"...it later became the de facto national anthem of the Confederacy during the Civil War.
I never claimed Confederate solders and the Confederacy were not enemies. I said so was Japan and Germany and we have museums honoring their culture. Both killed many more people than the CSA and Japan enslaved Korean women for sex slaves.
I have no particular affection for the CSA flag or symbols, but neither do I want people to tell others what they can display. That includes, for example, marches in public places in which they might choose to carry the flag.
