As is required in this PC world, I must preface this by making clear that I fully subscribe to Dr. King's foundational premise that a man should be judged by the content of his character and not by the color of his skin. And because I believe this, the ideas of "supremacists" of any race are abhorrent to me. I don't understand how people can raise their children to hate groups of people ... but to be honest, I think that's just what identity politics does. We have been dealing with identity politics on the Left for decades, and perhaps what we are now seeing is the rise of right wing identity politics. It's all despicable to me, because politics should be about ideological differences, not about racial animus. I fear the country is in bad shape, in part due to the fact that 24/7 cable news makes money off this divisiveness, it keeps us glued to their networks and makes them money. So expect to see more urban strife, unless you can find a way to turn off the television and get your news from more sober sources.
There is a very good reason why Confederate monuments exist in town squares from Virginia to Texas: Lincoln would most definitely have approved of them. Remember in his 1864 Inaugural Address, Lincoln said "With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations."
Note that Lincoln did not say this applied only to the wounds of the North. Lincoln was concerned about the wounds of ALL Americans, ALL veterans, ALL widows, ALL orphans. After all, he prosecuted this war with all he had in order to preserve the Union of ALL Americans, right?
Lincoln had the opportunity to have Lee, Longstreet, etc. hanged, but he famously asked Grant to "let 'em up easy". Lincoln actually had enormous respect for Lee, and saw him as a partner in putting the country back together again (a view he did not hold for Jefferson Davis). Sadly, of course, Lincoln didn't live to do create this partnership, and his successor, Andrew Johnson, behaved more punitively towards the South. Even so, no one dared to treat Lee as a war criminal, although some firebrands in the North talked that way.
In the years after the war, many former Confederate leaders behaved in an exemplary manner, of course none so famously as Lee, who advised against a terrorist resistance to the Union, and who later served as President of Washington College, which is now known as Washington and Lee University.
Fast forward to today. While there can be no doubt that bigotry exists in the US, and that it is most heinously exemplified by these neo-Nazis, we have to ask ourselves if the benefit of "feeling good" about erasing such symbols of the Confederate past in the US South is worth painting all Southerners who respect and admire people like Robert E. Lee as racists. Do we really want to push the Right into the same kind of identity politics that has beset the Left? That's exactly what demagogues like Steve Bannon want ... because of the counter-reaction it is sure to create.
God help us all if we cannot tolerate those who find virtue in Robert E. Lee. To call him a "traitor" is to ignore that he was loyal to his "country" which to him was Virginia. Before the Civil War, the "United States" was a plural noun, as in "the United States are wonderful". After the war, it became a singular noun, as in "the United States is wonderful". Calling Lee a traitor is the equivalent of charging him with an ex post facto crime.
True, he was a slave-owner (most of his slaves inherited through his wife, a descendant of George Washington). But if I recall, a clear majority of the signers of the Declaration of Independence were slave owners. It is an ethical black mark on an otherwise honorable man.
