I just want to clarify something. I find the reaction that some people have when I say (as I fairly often do) that I'm an atheist... well, disappointing. The most common responses, particularly from those who are theists, are "well that's just another religion" or "you're just a another kind of fundametalist". These are reactionary, unflatteringly glib, and smack of indoctrinated aversion. So I'd like to take this opportunity to clarify a few things.
Atheism is not a religion. It is the conscious, deliberate absence of religion.
