Objective, educated people know that historical issues are rarely as simple and cut-and-dried as school textbooks portray them. This is especially true for issues such as the Confederacy. A few more facts on the issue:
-- When in late 1864 the Confederacy began to debate emancipation for slaves who agreed to serve in the army, letters to editors in Southern newspapers ran heavily in favor of the idea. This should not be shocking. Fewer than 10% of Southern citizens owned slaves, and 2/3 of Southern households did not have slaves.
-- Liberal historians frequently misquote the Confederate bill that authorized emancipation for slave soldiers in order to make it appear that the bill did not authorize any change in the slaves' status. If you read the bill, you'll see it did authorize such a change. Moreover, when Jefferson Davis issued the executive order to implement the bill, he added the stipulation that slaves had to volunteer for military service, that no slave could be forced to serve against his will.
-- Many, many non-slaveholding Southerners harbored considerable resentment against the planter class, i.e., slaveholders who owned 50 or more slaves.
-- The radical slaveholders and slavery apologists were known as Fire-Eaters. Nearly half the members of the Confederate Congress were Fire-Eaters. To give you some idea of how radical they were, Fire-Eating Southern newspapers blasted Robert E. Lee when he publicly supported gradual emancipation in late 1864 and early 1865. Until then, criticism of Lee in Southern newspapers had been rare and mild.
-- There were two groups of Fire-Eaters. You had sincere, principled Fire-Eaters such as Robert Barnwell Rhett, who truly believed that the slaves were happy with their situation and that emancipation would be harmful for slaves, and who were shocked and disturbed when they realized this was not true. But then you had other Fire-Easters such as Thomas Hindman, who were immoral and who cared nothing for slaves and viewed them as little more than cattle.
-- The Fire-Eaters were the ones who spread false, inflammatory stories about Northern abolitionists starting fires in the South, freeing slaves, urging slaves to stage a violent revolt, etc., etc.
-- The Fire-Eaters were also the ones who led the charge to reject the 1860 election results and to push the Deep South states to secede. In contrast, men like Davis and Lee urged restraint and negotiation and initially spoke against secession.
