Your Lincolnian bullsh*t artistry aside, there are many more types of inequality than moral and intellectual. Lincoln readily said that blacks were not equal in color and also said that he opposed social and political equality with them. That makes him a white supremacist by any definition of the term. Live with it.
"I will say then that I am not, nor ever have been, in favor of bringing about in any way 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." - Lincoln, 8/17/1858.
"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.... It is better for us both, therefore, to be separated." - Lincoln, speaking to a group of former slaves 8/1862
Yeah, he wanted them out of the country entirely. Once it was shown that they were not willing to leave voluntarily he sought another alternative, which included A: Getting as many as possible into Union army uniforms and B: advocating that those who were enlisted were then able to vote.
A white supremacist would not have done that.
