I'm not saying he was racist, but he wasn't as goody goody as some want to think.
Just think about it:
Why did he overturn Gen. Fremont's declared freedom of slaves in 1861?
Also, Lincoln did nothing to abolish slavery in the states that the government (he) controlled. He only abolished it in the states that he didn't control at the time.
He's also been quoted as saying:
"I will say then that I am not, nor ever have been in favor of bringing about in anyway the social and political equality of the white and black races - that I am not nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people; and I will say in addition to this that there is a physical difference between the white and black races which I believe will forever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I as much as any other man am in favor of having the superior position assigned to the white race."..........September 18th, 1858
"No amendment shall be made to the Constitution which will authorize or give to Congress the power to abolish or interfere, within any State, with the domestic institutions thereof, including that of persons held to labor or service by the laws of said State.".... Joint Resolution of Congress, Adopted March 2, 1861
"I declare that I have no intention, directly or indirectly, to interfere with slavery in the states where it exists."........Inaugural address March 1861
"My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it......" August 22nd, 1862.
So don't act like Lincoln was this loving, gentle man. He was only thinking about what would benefit him and get him in to office.
