Intelligent
Theist: I know that neither of you believe in God, but perhaps I can convince you otherwise.
Athy Person: I'm athiest! I know that the bible is false
and that there is no God. SCIENCE proves it, so it must be true! I don't need to talk about it, my faith lies in SCIENCE.
Legitimate Atheist: Yes, you are quite
athy (speaking to Athy Person). I would love to discuss religion with you (speaking to Theist).
Athy Person: Thank you.
