Perhaps, I have it wrong but I always detect a bit of longing whenever that question is posed. To me it's like asking, "What could that drunk-driver have done to kill not, just your parents, but you and your kids also?" I guess that's hyper-emotional. Perhaps it's like the Russian contemplating how Hitler could have succeeded. I don't know. I make no pretense of objectivity. It's just how it feels.
That said, James Roark and William Cooper really deftly handled a question about what scholars could do to restore "respect for the Confederate flag." Roark made a great riposte by contrasting the waving of the Confederate Flag with claims of Southern hospitality.
EDIT: Yeesh. The lectures are great, but skip ahead to the questions. Last question--"Did white Southerners get a bad rap for slavery?" Drew Faust crushed that one, though.
