However, he [Lincoln] did NOT think that blacks were necessarily inferior, just that they couldn't live side by side with whites.
I'm sorry, but Lincoln actually did think they were inferior. He said, in one of his Lincoln-Douglas speeches, "I will say, then, that I AM NOT NOR HAVE EVER BEEN in favor of bringing about in any way the social and political equality of the black and white 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 will ever 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." And in case you think this was just speecifying in front of the racists in the crowd, he said the following virtually identical statement to a delegation of BLACK LEADERS who had come to the White House to discuss the issue of possible colonization...""Why should the people of your race be colonized, and where? Why should they leave this country? This is, perhaps, the first question for proper consideration. You and we are different races. We have between us a broader difference than exists between almost any other two races. Whether it is right or wrong I need not discuss, but this physical difference is a great disadvantage to us both, as I think your race suffer very greatly, many of them by living among us, while ours suffer from your presence. In a word, we suffer on each side. If this be admitted, it affords a reason at least why we should be separated. It is better for both, therefore, to be separated." So it seems clear that he did consider that, because of the PHYSICAL DIFFERENCES (i.e. skin color) of the black race, that they were inferior.

"He wanted to free them and send them back to Africa at first... eventually, he settled for simply wanting to free them....His hope was that it would die off on its own and the blacks could be shipped back to Africa. The ACW forced him to change a lot of his views...."
What forced him to change his views regarding sending blacks back to Africa was the fact that the blacks themselves refused to go along with it. Lincoln never abandoned his own belief in colonization.
