No member of my family ever lived south of the Mason-Dixon line until my cousins moved to Baltimore in 1979. I have two ancestors who were directly involved in the Civil War and they both fought for the Union - which is why I'm a member of the Sons of Union Veterans.
This is not outcome-based history to improve your self-esteem.
My self-esteem is intact. I don't need to build a chest-beating statue in Richmond to remind myself that my great-great-grandfather marched with Grant.
Old Town Albuquerque still has on display the Texas cannons captured at the Battle of Glorietta Pass.
Great. Richmond has the Confederate White House on display that was captured during the Virginia Campaign. Unless the statue of Lincoln in question was present during the military action I don't see any good reason to display it.
Apparently Lincoln thought it important enough to be present in person, with his son, very shortly after the military action.
Take it up with him, or get over it.
I don't see the problem: 'Kandahar' is named after 'Al Kandhar'--Alexander the Great. Leningrad was named after Lenin when the Bolsheviks won and then re-renamed Petrograd (IIRC) after the Nationalists won. We renamed a lot of America with european names in lieu of the original indian names....
At least they didn't rename Richmond 'Lincolnistan' or Lincolnstinia....
I assume based on your view on the Lincoln statue that you support 'Native American' causes for the same reasons?
After all, America is as much the indians as the south is confederate....
