It`s derogotory to those who actually think he was doing it for only one purpose, the humanitarian one, when in faact he freely admittted it was a strategic war decision .
Lincoln`s views of negros, “I have declared a thousand times, and now repeat that, in my opinion neither the General Government, nor any other power outside of the slave states, can constitutionally or rightfully interfere with slaves or slavery where it already exists.”
“My declarations upon this subject of negro slavery may be misrepresented, but can not be misunderstood. I have said that I do not understand the Declaration (of Independence) to mean that all men were created equal in all respects.”
“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 who are these people?
That doesn't state Lincoln's view of negros, it states his view of the law. When you see the same error a hundred times, and see it corrected, you start to doubt the honesty of the person offering it.
