It is not possible for you to prove Lincoln was not a racist, there is far too much evidence to the contrary.
So you say. I say different, but to get to the heart of the matter, let's hear your definition of a 'racist.'
By today's standards, yes. But by those same standards Bobby Lee is a vile, despicable racist. So is Thomas Jackson. So is Jeff Davis. So is every Southern leader you care to name. No comment on them? No criticism? No condemnation? Being racist is all right if your a rebel, is that it?
