I see a number of contradictions in his article that cannot be explained without unreasonably stretching his meaning. For example, in his list of contradictions he says that G-d wrote something in Numbers and that G-d wrote something in Deut. But in the summary he says there were two authors. So it appears that the simplest approach is that more than one author wrote the article, and at least 2 of them were drunk.
Seriously though, I am an academic myself, and purely from that viewpoint alone this article is garbage. He forced an article to present a predetermined premise. If this is representative of his caliber of work, I would drop him from my program.
