Your “historic icons and monuments” are of traitors and losers. Most were erected in the early 20th century, not immediately after the end of Civil War. Actually, the time from the end of the War and the erection of most monuments was less than the time from the end of WWII to now, so maybe it’ll be OK for Germans to start erecting monuments to their icons like Hitler, Goring, Himmler, Rommel, etc. Unfortunately, I suspect that you would probably support that too.
As others have commented, I suspect your attitude toward slavery would change greatly when the leg chains are put on you. Don’t worry, we’ll treat you well, and even let your family work alongside you.
