I think he would be on the spectrum because if you listen to this youtube video from his website, you will see what I mean.
He does not state at any stage his is on the spectrum but his social history at school suggests otherwise.

He fits the criteria for his communication anomalies, especially as he was growing up. Like he had a stutter and required speech therapy.
Social skills? I would say yes because in this video he tells his story of being a subject of getting picked on at school.
I believe he does has very obsessive and repetitive interests, particularly with religion.
He also admits to being a bit "dawkie" at school and still believes he is to some extent.
