We can’t totally erase history and judge people on their single sin. Doak Campbell was not a general segregationist. My understanding is a comment taken out of context in a single speech.
are we going to erase Clinton and Obama because they were liars? Are we really going to erase Washington and Jefferson because of a few slaves and not look at the totality of their contributions? Should we erase Lincoln because of his indifference to slavery at the beginning of the war? We can’t erase history and learn not to repeat it at the same time.
