Huh?
An excerpt from The Mythical Lincoln, by Thomas DiLorenzo --
"You, and others like you have done more, according to your abilities, to prevent the peaceful abolition of slavery, than any other men in the nation; for while honest men were explaining the true character of the constitution, as an instrument giving freedom to all, you were continually denying it, and doing your utmost (and far more than any avowed pro slavery man could do) to defeat their efforts. And it now appears that all this was done by you in violation of your own conviction of truth. In your pretended zeal for liberty, you have been urging on the nation to the most frightful destruction of human life; but your love of liberty has never yet induced you to declare publicly, but has permitted you constantly to deny, a truth that was sufficient for, and vital to, the speedy and peaceful accomplishment of freedom. You have, with deliberate purpose, and through a series of years, betrayed the very citadel of liberty, which you were under oath to defend. And there has been, in time country, no other treason at all comparable with this." - Open letter to Senator Charles Sumner, 1864
"The pretense that the "abolition of slavery" was either a motive or justification for the war, is a fraud of the same character with that of "maintaining the national honor." Who, but such usurpers, robbers, and murderers as they, ever established slavery? Or what government, except one resting upon the sword, like the one we now have, was ever capable of maintaining slavery? And why did these men abolish slavery? Not from any love of liberty in general --- not as an act of justice to the black man himself, but only "as a war measure," and because they wanted his assistance, and that of his friends, in carrying on the war they had undertaken for maintaining and intensifying that political, commercial, and industrial slavery, to which they have subjected the great body of the people, both black and white. And yet these imposters now cry out that they have abolished the chattel slavery of the black man --- although that was not the motive of the war --- as if they thought they could thereby conceal, atone for, or justify that other slavery which they were fighting to perpetuate, and to render more rigorous and inexorable than it ever was before. There was no difference of principle --- but only of degree --- between the slavery they boast they have abolished, and the slavery they were fighting to preserve; for all restraints upon men's natural liberty, not necessary for the simple maintenance of justice, are of the nature of slavery, and differ from each other only in degree." - No Treason, 1870
