Clarification not accepted. Atheism is "a" (a prefix meaning not) + theism (a root word meaning god). Thus, atheism literally means not believing in a god. Thus, atheism is not a religion.

Agnosticism is a cop out that says the human mind is not capable of comprehending whether or not God exists. This stance is false because it is easy to prove that God does not exist.

1 percent of us are clinically insane?

Richard Dawkins in his book The God Delusion claims that anyone who believes in God is delusional (i.e. insane).

Anyway, congrats on your higher than mine views and reads.
