Symbols of the Confederacy deserve space in a well-curated museum, with full and factual information on slavery in the US and its aftermath. These symbols do NOT belong on public display. Germany remembers and teaches about Nazi Germany, but they don't fly the Nazi flag or glorify Nazi generals and leaders. Acknowledging history, learning all its facets is important. But celebrating tyrants and tyranny - and those who defended them - is neither necessary nor advisable.
