Define "Confederate sympathizer". Does it mean one who believes the Confederacy had a moral and just cause or just somebody who thought that the South should've been left alone? Because if it's the latter I don't see how it would make them hypocritical unless one is taking an "all or nothing" approach (ie if they "like LBJ" they agree with everything he did blah blah blah).
I mean someone who felt that the South was completely justified in leaving the Union. I should probably note that he wasn't a racist, just a states rights supporter.
