When a person tells you he or she is a Catholic, Conservative, Liberal, Anarchist, apolitical, agnostic, polytheist, amoral, etc., what do each of these tell you that person is not? Or is atheist the only term used completely and only by people who (for some ridiculous reason) wish to identify themselves ideologically, philosophically, epistemologically, and/or intellectually in terms of a singular definition that describes that which they aren't, rather than what they are or what they think or believe?
