Ok, let's try to not use leftist tactics like showing quotes out of context here. He was calling Trump "Abraham Lincoln here" in a denigrating manner, and doing exactly the same thing, taking Trump's own words out of context, twisting them around and spinning a new narrative.
And if what I've read is true, Lincoln WAS a racist, but not a "horrible" one, despite what another commenter said. (Which has no value anyways, since to idiots like them, just doing something like drinking milk makes you a horrible racist).
From what I've read, Lincoln believed black people were inferior, but he didn't believe Americans, or anyone, had the right to enslave them. He believed they had the right to be free, but kept separate from whites, or sent back home to Africa, where they'd be happiest.
