Neutral. His politics are horrible but I don't think he's necessarily a bad guy personally.
I generally don't consider politics when evaluating whether someone is a good person or not, but I find it very hard to imagine someone who has said the things he's said being a decent human being.
I'm personally extremely offended by his comments regarding slavery and the Confederacy, as if people like him had gotten their way, many of my closest friends and even my SO would still be enslaved to this day - I find it morally disturbing to imagine someone saying the things he's said as it relates to those issues, and I can only hope one day he finds God or something similar, and realizes how truly evil and despicable the Confederacy and slavery as an institution were.
