Sounds like a Yankee dis-information plan to me.
No, it's American history.
A lot of Southerners have been propagandized out of taking pride in their Unionist forebears and a lot of Northerners have conveniently forgotten about their defeatist, Copperhead forebears.
The historical fact is that "the American South" and "The Confederacy" are not synonyms.
The secession "vote" in Georgia would have done Al Gore's Florida team proud.
The truth always sounds that way to those who do not accept it.
