I agree that he's quite probably not racist. He appears to have a fascination with computerised randomisation as a means of divining words from God. This would explain some of his (otherwise unintrospectable) comments. And it also leads me to believe that his frequent mention of the CIA and the n-word has some special, possibly even internally consistent, meaning to him, of which we are simply unaware. I am at least able to pick up on some of the religious allusions he makes elsewhere. That doesn't make him sane. But it might perhaps excuse what would otherwise be unacceptable.
