Easy. The Civil War wasn't about slavery.
That would be easy if it were true, but it's not. That is history revisionism at it's worst, and frankly at it's silliest.
Every significant Confederate document include very prominent and specific language about slavery making it very plain and clear succession was primarily about slavery. Before re-writing history one must burn the books.
Given the majority of people in the south (that did the fighting) did not own slaves, what would you assume is the reason they fought?
and what were the "every significant confederate documents" you reference?
Who exactly attributed the "significant" moniker to these doucments?
Of course the Confederate Constitution and the Articles of Succession from all the seceding states, and primary among those the five states that included Declaration of Causes, in which slavery was the first item mentioned in most cases.
History has been effectively re-written many times throughout history, but in each case they removed all evidence to the contrary. The entire premise that slavery had little to do with the civil war is, on it's face, ludicrous. That these documents exist only attests to that obvious fact.
