I agree on Rand and Libertarianism - although (as an Objectivist myself) it may interest you to know he's not an Objectivist, as he objects to several aspects of Rand's philosophy. I still have his suggested reading in that area on my TODO list.
But racism, and paranoia? I'd (seriously) like to see evidence of those if you have them. Nothing I have seen him write or do suggests he treats people in any way other than as individuals, on their merits alone.
Did you miss the blog article where he said a friend had told him that women were trying to have sex with OS leaders, so they could accuse them of rape?
Sounds pretty paranoid to me.
I might have been wrong about the racism stuff. I swear I saw some stuff, but I can't find it now, so I might have been confused with somebody else.
But at the end of the day, he's still an unpleasant person.
