Whether we like it or not, the big "S" is and always will be a part of any Civil War discussion. We have beat that word until it is much less than a string but we can always pull a thread out of it.
I think it is better to try to establish a cause for fighting or for not fighting and whether Robert E. Lee turned gray before he broke his hand or after is really of no consequence to how a War of such magnitude started.
So how are you T.S.?
