I think the nobility of Lee and Lincoln are in danger of being of being forgotten and replaced by the falsehood that protesting builds a nation rather than constructive effort.
Let a statue of Medgar Evers be erected directly across from Lee so that their gazes meet and people be provoked to think.
But perhaps to your larger point. I do think some of this stuff is ridiculous. The problem, as i see it, is that so many of these symbols are enshrined in official symbols and other places where they have no business. If you want to heal and not divide, lets start with removing symbols with questionable (at best) pasts from the objects that represent our government.
Don't put the same symbol that flew over the confederacy on the flag of a state that is 37% black (or any % black, for that matter).
