Lincoln was clearly a racist and separatist. It is not possible to read the words that came out of Lincoln's mouth and arrive at any other conclusion. That is why Black historians do not write glowing biographies of Lincoln.
I think your obsession with ignoring the half-century of racist quotes issues by Lincoln in order to cling to some perverted myth, would lead most thoughtful persons to think you were incapable of rational, independent thought.
The evidence is inescapable.
Lincoln said he was in favor of the new territories "being in such a condition that white men may find a home."
Lincoln, Alton, Illinois, 10/15/1862
"His democracy was a White mans democracy. It did not contain Negroes." Oscar Sherwin
Lincoln's dream did not contain Indians or even Mexicans who he referred to as "mongrels."
Lincoln, CW 3:234-5
"Resolved, That the elective franchise should be kept pure from contamination by the admission of colored votes."
That got Lincoln's vote, January 5, 1836.
"in our greedy chase to make profit of the Negro, let us beware, lest we 'cancel and tear to pieces' even the white man's charter of freedom"
Lincoln, CW 2:276
Translation for the intellectually challenged:
The White Man's Charter of Freedom = The Declaration of Independence
Lincoln wanted the territories to be "the happy home of teeming millions of free, white prosperous people, and no slave among them"
Lincoln, 1854, CW 2:249
The territories "should be kept open for the homes of free white people"
Lincoln, 1856, CW 2:363
"We want them [the territories] for the homes of free white people."
Lincoln, CW 3:311
If slavery was allowed to spread to the territories, he said "Negro equality will be abundant, as every White laborer will have occasion to regret when he is elbowed from his plow or his anvil by slave n-----s"
Lincoln, CW 3:78 [Lincoln uses the N-word without elision]
"Is it not rather our duty to make labor more respectable by preventing all black competition, especially in the territories?"
Lincoln, CW 3:79
