In Nashville (near where I reside), there is now a debate about what to do--if anything--with a bust of Nathan Bedford Forrest, that is currently in the state capitol building.
Some want it removed entirely--and, at best, given a new home (perhaps in a museum).
Others want it to remain exactly where it now is.
And I can see both sides of this debate.
On the plus side, he was an absolutely brilliant military tactician--more so than even Robert E. Lee, in my opinion.
On the minus side, the man was a slave trader (prior to the Civil War) and the first Grand Wizard of the KKK (following the Civil War). And he even presided over (and encouraged) the massacre of black soldiers at Fort Pillow in 1864, after they had already surrendered. (Note: In all fairness, the man subsequently denounced the KKK, when it became especially violent. Even so, he was certainly a virulent racist--even by the standards of that time.)
So this is really not an easy call, in my opinion.
