I think that Sherman's March is to the Confederate Lost Cause what Ferguson is to Al Sharpton and his ilk. An incident that is used to rally around and inflame passions but at the end of the day is based mainly on myth and inaccuracies.
Yes, but the myth and inaccuracies are primarily from those who take the side that Fedzilla had a right to force people to remain in the Union.
When asked how they can defend a position so at odds with our founding principles (as articulated in the Declaration of Independence) their only answer is "Slavery!!!!" But when it is pointed out that every state was a slave state in 1776, they simply ignore or rationalize the point.
The fact is, the North could not invade the South for the stated purpose of forcing them back into the Union without violating the very principles upon which this nation was founded. Their arguments invariably boil down to a form of "Might makes right."
That's a pretty fair analogy. In point of fact, all the 'Sherman Hate' in the South didn't actually crop up until 30+ years after the war when the Lost Cause myth-makers got into high gear.
Hell, even Confederate General Joe Johnston served as a pall bearer at Sherman's funeral. Johnston was the guy who tried to stop Sherman in North Georgia and then later in the Carolinas.
