Well, if I have to choose between George Washington and Patrick Henry, both men who stated that they wanted to be known as Americans and not Virginians, or Robert E. Lee, my vote goes for Washington and Henry.
Lee was a great man, who did a great deal in sparing the South further damage by acknowledging that the war was over and it was time for Southerners to consider themselves as Americans again.
Go ye and do likewise.
Apparently, you didn't read some of Lee's later writings.
He wasn't so happy with Reconstruction, and wished he had never surrendered.
