No it’s revisionist what you’re trying to do. Lincoln had said to Grant before he went to Appomattox “Let them up easy’’. Now what do you suppose he meant by that? For Gods sake how long are you going to go on fighting an immoral war your ancestors deliberately started and lost?
The only thing immoral around here is you.
By the way - Davis wasn’t at Appomattox. And Lee didn’t surrender for the Confederacy. He surrendered his Army of Northern Virginia. The Army of Tennessee was still in the field, as were forces in Texas and Oklahoma.
