Lincoln the secessionist:
"Any people, anywhere, being inclined and having the power, have the right to rise up and shake off the existing government, and form a new one that suits them better. This is a most valuable and most sacred right - a right which we hope and believe is to liberate the world. Nor is this right confined to cases in which the whole people of an existing government may choose to exercise it. Any portion of such people that can, may revolutionize, and make their own, of so many of the territory as they inhabit." - Abraham Lincoln, January 12, 1848.
Lincoln the racist:
In his new book, Forced Into Glory: Abraham Lincoln's White Dream, black American author, Lerone Bennett, presents historic evidence supporting the theory that Abraham Lincoln was, in fact, a devoted racist harboring a life-long desire to see all black Americans deported to Africa.
Bennett suggests that as a young politician in Illinois, Lincoln regularly used racial slurs in speeches, told racial jokes to his black servants, and vocally opposed any new laws that would have bettered the lives of black Americans.
Key to Bennett's thesis is the 1863 Emancipation Proclamation which, Bennett argues, Lincoln was forced into issuing by the powerful abolitionist wing of his own party. Bennett asserts that Lincoln carefully worded the document to apply only to the rebel Southern states, which were not under Union control at the time, thus resulting in an Emancipation Proclamation that did not in itself free a single slave.
At one point, Bennett quotes William Henry Seward, Lincoln's secretary of state, who referred to the proclamation as a hollow, meaningless document showing no more than, "our sympathy with the slaves by emancipating the slaves where we cannot reach them and holding them in bondage where we can set them free."
Henry Clay Whitney, a close friend of Lincoln, is quoted by Bennett as saying the proclamation was "not the end designed by him (Lincoln), but only the means to the end, the end being the deportation of the slaves and the payment for them to their masters - at least to those who were loyal."
