This is what I wrote for a Christian asshole who asked "How is atheism not a religion?"

"How is atheism not a religion?"

"Atheism is the world of reality, it is reason, it is freedom, Atheism is human concern, and intellectual honesty to a degree that the religious mind cannot begin to understand. And yet it is more than this. Atheism is not an old religion, it is not a new and coming religion, in fact it is not, and never has been, a religion at all. The definition of Atheism is magnificent in its simplicity: Atheism is merely the bed-rock of sanity in a world of madness."
-- Emmett F. Fields

One more thing: People who are not religious do not belong to a religion. Any child can figure that out. But you are so fucking dense you can't understand anything.
