Looking for Lincoln: the great emancipator or white supremacist?

An interesting documentary that tends to focus on questions of Lincoln's racism vs his white supremacism:  emotionally-charged terms whose meanings are quite divergent within the context of their times.  (Personally I try to be cautious with the word "racism," which I hold to be an imprecise term having too many different meanings that don't stand up very well at all over centuries.) I don't altogether agree with the picture that's presented here regarding the hows and whys of the Emancipation Proclamation: see my previous post on the matter.
