His butt would be my guess. Any truth to be found in there was probably accidental.
Do you disagree with the part regarding the "Emancipation" Proclamation? Because if you go and read the actual document you will find that it specifically leaves out the slaves in Union states, the only ones Lincoln could have really freed.
Do you disagree with the facts regarding the tariff issues of the time? If so you should research the issue more and read what people of the time had to say on it:
In December 25, 1860 South Carolina declared unfair taxes as a cause of secession in her Address of South Carolina to Slaveholding States: “The British parliament undertook to tax the Colonies, to promote British interests. Between taxation without any representation, and taxation without a representation adequate to protection, there was no difference.” “And so with the Southern States towards the Northern States, in the vital matter of taxation, they are in a minority in Congress.” “The people of the Southern States are not only taxed for the benefit of the Northern States, but after the taxes are collected, three-fourths (75%) of them are expended at the North.” (Paragraphs 5-8)
Only 5 of the 13 Confederate States mentioned slavery issues in their Secession Ordinances, i.e., the return of fugitive slaves, slavery in the U.S. territories and Federal abolition. By leaving the voluntary Union, these States abandoned all claims regarding the first two and the issue of Federal abolition was entirely eliminated as a cause of war by Lincoln’s First Inaugural Address and the Corwin Amendment. The only issue of contention remaining was the 40% Federal sales tax on Southerners, which required a compulsory Union to collect.
Lincoln states why he was fighting the South on April 19:
“Whereas an insurrection against the Government of the United States has broken out and the laws of the United States for the collection of the revenue cannot be effectually executed therein: Now, therefore, I have further deemed it advisable to set on foot a blockade of the ports within the States aforesaid.”
After the South had been forced back into the (now) compulsory Union under the 40% tax rate, Federal tax revenues mushroomed 300% to $170 million per year. Before the war, while the South was in the Union under the 20% tax rate, revenues had been $50 million per year. Source: U.S. Census Bureau Balance of Payments And Foreign Trade: 1821-1945 (Page 248)
