Brunout its not a religion to not have a religion. Just like its not a religion to not believe in leprechauns, Xenu, Zues, or Baal. You assume you know what people believe when they don't sacrifice their life in someway to one of the thousands of deities. You are wrong, all non-theists aren't atheists, just as all theists aren't christian. Again, just as your belief in  god(s) you assume too much with no credible information back it up.
