In 1864, black Union troops were involved in operations against Lee's army outside Richmond and Petersburg, and some of them are taken prisoner. Lee … - Brooks D. Simpson

[I]if you think that this whole matter can be reduced to whether we should allow the display of the Confederate flag, you really aren't advancing the discussion very far.

I think it's time for all this discussion about the proper display of the Confederate flag, which in some quarters appears to obscure the enormity of the massacre at Charleston, to get to the heart of the matter. You tell me. Should the Confederate battle flag, including its versions as the Army of Northern Virginia flag, the Army of Tennessee flag, and the Confederate navy jack, be flown outside, period? Do you favor the removal of the Confederate flag flying on the grounds of the South Carolina State House? Why? If you believe that the flying of the Confederate battle flag on the grounds of the South Carolina State House should cease, are there any conditions when a Confederate battle flag should appear outside? Should the Confederate battle flag be banned from public display elsewhere? T-shirts, bumper stickers, headgear? Are your restrictions limited to the Confederate battle flag alone, or do they extend to other flags flown by the Confederacy, such as the trio of national flags?

The Lee myth. Lee being above slavery, Lee being in fact anti-slavery, is essential to the neo-Confederate argument that it's not about race, it's not about slavery. They've done a very good job of covering up Robert E. Lee's actual positions on this.
