I get a lot of Black and White thinking from the guy. It seems to me that he regards “Belief” as an all or nothing proposition. Basic “Theist” thinking. If you believe in something it is 100% The idea that belief is alocated to the degree of the evidnce is foreign to him. He is using an extremely narrow definition of belief, "Dogmatic, Unevidenced, acceptence of a claim. " This of course is not the only type of believe out there. In fact it is a very small percent of the possible ways to believe.
I believe he is just stupid. I support that remark with the fact that he can look evidence in the face and still deny that he is seeing evidence. Show him a white rabbit and say “Look, this is a white rabbit.” And you will get, “Well, philosophically it is a cow.” He is dishonest and not willing to have an actual conversation.
