Supernaturalism is a distraction. Theologists defend supernaturalism as an indirect way of defending whatever God they want to believe in. See http://www.uncrediblehallq.net/2011/06/24/atheism-is-just-thinking-there-arent-any-gods/.

The sequences are not specifically tailored to convince people of atheism. They are rather a more general set of tools in going about and reasoning about the world. So don't over-ascribe relevance to atheism many of the philosophical ideas you see in there.
