I received an email from a nontheist that is somewhat critical of the idea of "naturalism vs. theism" as a debate topic because (1) not all non-naturalistic views are theistic, and (2) the topic involves a comparison of a general hypothesis (metaphysical naturalism) with an incompatible but very specific hypothesis (theism). In his opinion, the debate topic should be either "naturalism vs. supernaturalism" or "nontheism (or atheism) vs. theism."
