I was going to likewise suggest, again, in response to Erod, that with the cases of Lincoln, of Jefferson, and so forth, the matter is always far from settled. Just think about how Lincoln could be viewed by Southern Historians around the time after reconstruction ended? A significant change happened there. The change could still significantly end if we thought his control of the Union during the war was extreme and at contrary to our political morals, as a great many Libertarians brought up. With Jefferson, I can't tell you how many times I have walked around discussing Jefferson with people who will be teaching our young people, and having them respond with 1) "Says the man who owned slaves" 2) "Says the man who slept with his slave". There is a significant amount of contempt for Jefferson because of his relationship to slavery and the high likelihood that it was he who fathered a child from Sally Hemmings (though we have no means of identifying exactly that he was the father of said child).
