It does contain a bit of a false-dilemma though: It asserts that the only "real" form of god involves a specific flavor of Christian evangelical prayer-interventionist deity, and that the only other option is (B) no god(s) exist at all. I'm very much in favor of showing how silly or self-contradictory (A) is, but it is fundamentally unsound to jump from that to asserting (B) is true.
