One of the first things which alerted me to that was the house turned into a museum (Longstreet if I remember correctly, in Knoxville). We were still tourists and had time to visit places in the city. The nice lady gave us a great tour and then said she was thrilled that General Robert E. Lee had just regained his citizenship. Things run deeply in sentiment sometimes.
I am most interested in how the Southern Baptists broke from the Baptist Church. It was over the question of slavery. Most of the Baptists I know have little outward hostility toward African-Americans, yet define themselves as much by which part of the Baptist Church they belong to==Missionary, Primitive, etc.
I live down the Parkway from Friendsville which had its Quaker beginnings from that time. One of our Maryville neighbors had parents whose families came from both sides of the question. A nice place to see history, for me, is Andrew Johnson's home. It is so well taken care of. It's a good way of seeing how a man of little learning and no wealth managed to play a big roll in Tennessee history. And his history also tells us a lot about troubled times in politics after the war.
Just as an aside: Will Lamar run for Senate again?
