One of my wife's forebearers was the last surviving veteran of the Revolutionary War when he expired near Ash Grove, MO in 1866.
Interestingly, prior to the nearby Battle of Wilson's Creek, he was visited by units from both the Federal and Confederate forces involved. Both honored him with a nineteen-gun salute.
I think the story is illustrative of what was in the hearts of both sides: Love for their country.
I've lived in the Deep South and honestly don't know a single soul who is "still fighting the Civil War" or who supports slavery in any way. Sure, they complain about Yankees...but it's good natured.
Recall that one of the reasons the libs hate the South is because they describe it as "The Most Patriotic Part of America". Which, by many measures, it is.
In my humble opinion, your concerns are misplaced...
Don’t know anyone still fighting The Civil War? Dude, are you not paying attention? They’re all over this thread.
