A CSA patriot is a USA traitor.
Pretty much.
However, IMO, at the time it was possible for an entirely honorable man to choose to follow either his nation or his state.
Davis and Lee chose to follow their states. I have never seen any reason to believe they made their choices for anything but honorable reasons.
Another Davis, the Alabamian Grimes, was one of the best Union cavalry officers. http://www.iment.com/maida/familytree/davis/davis.htm
And of course one of the most inappropriately ignored Union generals, Henry (The Rock of Chickamauga) Thomas, chose to follow the Union despite having his family disown him and his state confiscate all his property.
Such men were placed in a position where they had to choose between treason to their nation and to their state.
