Geeze, there are some really strange notions about atheism in some heads. I am an atheist by some definitions, in that I don't believe for a minute in an anthropomorphic, self-centered omnipotence poking His nose and fingers into human affairs. I don't believe in Zeus, either, for that matter, or Zarathustra's Ahura Mazda. But I am not insensitive to the inklings and whispers of primal Causation that find their way into the human imagination, and I honor the genuine efforts to listen to them wherever found. I just don't think any of the mainstream definitions of godhood, Lordhood, or deity have anything to do with the substance of the issue.
Furthermore I am not unhappy, crotchety or grumpy most of the time. I am more inclined toward levity and the celebration of consciousness and good spirit.
Just in case anyone wants to correct their stereotypes or something.
