Here are two hypotheses about theism, atheism, and dismissive attitudes.

H1: for (some / many / most) theists, how dismissive a theist is to atheism is inversely proportional to how familiar said theist is to the best, most robust arguments for atheism*

H2: for (some / many / most) atheists, how dismissive an atheist is to theism is inversely proportional to how familiar said atheist is to best, most robust arguments arguments for theism

* For purposes of this post, replace “atheism” with “the positive belief that God does not exist”
