I may be the wrong person to ask that question of.  Two pieces of information before I continue - I was born in Vermont, and I am a Civil War junkie who has now been to every major battlefield and immersed myself in research what caused the war.  I see nothing in the memorials.  You go to Gettysburg or to Fort Sumter and you see the canons.  Travel to any of the battlefields and you see the same thing.  Just relics of the war.  They are reminders of our past, and nothing on earth can erase the racism that has been with us since long before the Constitution was adopted.  Do we remove the statutes of many of our presidents for their heritage?  Do we tear down the White House and the Capitol Building because the sweat and labor of blacks built them?
