He doesn't even notice this. He doesn't seem to make any attempt to understand anyone else's perspectives. He just says they're obviously wrong, using so many words and digressions that the reader assumes, coming to the end of a long paragraph, that there must have been an argument in there somewhere. It's the same style of argument George Steiner uses.

This is a common behavior among hedgehogs. I tend to just ignore it and figure out where this person's model works, and where it's overreaching.
