Worth repeating. 'Not holding a belief in X' is the ground state. It has to be, because there are literally an infinite number of things on The List of Things That One Could Not Hold a Belief In. You, for example, surely don't hold the belief that invisible dragons inhabit garages or purple mushroom men inhabit rotting logs in forests, or fnords like the taste of greeblies. The list is infinite. That is not the same as taking the stance that these things do not exist. Atheists*, at the base level, simply see God as one more thing on a list of inifinite things that are superfluous. * I should clarify: moderate atheists. Certainly, many atheists take an opinionated, strong stance that God does not exist. But that is not a required condition in being an atheist. Many atheists consider God just another non-issue. Atheist, literally, and simply, means without god. Much like aunicornist simply means without unicorns.
