The Civil War was so horrible there were no heroes. Sheridan and Sherman would have been considered war criminals at any other time, and it was only the Union changing their Articles of War to allow the targetting of civilians that prevented these two from being considered criminals. As bad as Lee may have been, he was the closest thing to decent on both sides. I have no problem with removing statues, but the whole thing is so lopsidedly biased it undermines what they're supposedly trying to achieve.
