Who said it was "no big deal?" Certainly not I. I said it was an issue and was even a major issue but that it wasn't "THE" issue. Much of the drive to expand slavery or to prevent the expansion of slavery was all about the power struggle between the two sides specifically in the US Senate. Just like today if I know your view on one issue, I can pretty accurately guess your views on many other issues most of the time so it was back then. If you were pro slavery you were against high tariffs and against centralized power. If you were against the spread of slavery or an abolitionist, you were pro tariff (which economically benefitted the North and hurt the South) and you were for centralizing ever more power in Washington DC (since you knew your side had more people and thus would have more power over the Southern states).
As for Ye Olde Cornerstone speech every PC Revisionist trots out, firstly Stephens was not very influential and held no real power. This was so much the case that he spent most of the war at home in Georgia. Nobody in the Davis administration listened to him. Next, if we are to take Stephens' word as gospel on this, what did he say about the North's motivation for starting a war?
“Their philanthropy yields to their interests. Notwithstanding their professions of humanity, they are disinclined to give up the benefits they derive from slave labor…The idea of enforcing the laws, has but one object, and that is collection of the taxes, raised by slave labor to swell the fund necessary to meet their heavy appropriations. The spoils is what they are after – though they come from the labor of the slave.”
What did he say about centralizing power in the federal government and usurping power from the states?
"If centralism is ultimately to prevail; if our entire system of free Institutions as established by our common ancestors is to be subverted, and an Empire is to be established in their stead; if that is to be the last scene of the great tragic drama now being enacted: then, be assured, that we of the South will be acquitted, not only in our own consciences, but in the judgment of mankind, of all responsibility for so terrible a catastrophe, and from all guilt of so great a crime against humanity."
What did the powerful and influential president of the CSA, Jefferson Davis say about the causes of the war?
Beginning in late 1862, James Phelan, Joseph Bradford, and Reuben Davis wrote to Jefferson Davis to express concern that some opponents were claiming the war "was for the defense of the institution of slavery" (Cooper, Jefferson Davis, American, pp. 479-480, 765). They called those who were making this claim "demagogues." Cooper notes that when two Northerners visited Jefferson Davis during the war, Davis insisted "the Confederates were not battling for slavery" and that "slavery had never been the key issue" (Jefferson Davis, American, p. 524).Precious few textbooks mention the fact that by 1864 key Confederate leaders, including Jefferson Davis, were prepared to abolish slavery. As early as 1862 some Confederate leaders supported various forms of emancipation. In 1864 Jefferson Davis officially recommended that slaves who performed faithful service in non-combat positions in the Confederate army should be freed. Robert E. Lee and many other Confederate generals favored emancipating slaves who served in the Confederate army. In fact, Lee had long favored the abolition of slavery and had called the institution a "moral and political evil" years before the war (Recollections and Letters of Robert E. Lee, New York: Barnes and Noble Books, 2003, reprint, pp. 231-232). By late 1864, Davis was prepared to abolish slavery in order to gain European diplomatic recognition and thus save the Confederacy. Duncan Kenner, one of the biggest slaveholders in the South and the chairman of the Ways and Means Committee of the Confederate House of Representatives, strongly supported this proposal. So did the Confederate Secretary of State, Judah Benjamin. Davis informed congressional leaders of his intentions, and then sent Kenner to Europe to make the proposal. Davis even made Kenner a minister plenipotentiary so as to ensure he could make the proposal to the British and French governments and that it would be taken seriously.
"I tried all in my power to avert this war. I saw it coming, for twelve years I worked night and day to prevent it, but I could not. The North was mad and blind; it would not let us govern ourselves, and so the war came, and now it must go on till the last man of this generation falls in his tracks, and his children seize the musket and fight our battle, unless you acknowledge our right to self government. We are not fighting for slavery. We are fighting for Independence, and that, or extermination." - President Jefferson Davis The Atlantic Monthly Volume 14, Number 83
“And slavery, you say, is no longer an element in the contest.” Union Colonel James Jaquess
“No, it is not, it never was an essential element. It was only a means of bringing other conflicting elements to an earlier culmination. It fired the musket which was already capped and loaded. There are essential differences between the North and the South that will, however this war may end, make them two nations.” Jefferson Davis
