You do realize the two terms are not mutually exclusive or interchangeable, don't you? Many ex-Christians are Atheists, but some are Wiccan, some follow Thor, some became Muslim, and so on and so forth.
And, once again, I am not an Atheist, and I would appreciate it if you would acknowledge this instead of wrongfully and incorrectly placing the label on me. Just because I think the character of Jehovah is one of the most unreasonable, vicious, cruel, monstrous, and sadistic characters in all of literary history doesn't automatically make me (or anyone else who thinks the same) an Atheist.
