Here is a link to an excellent documentary released by CNN a few years back-
Theists find Atheists very threatening. Secretly they have doubts about their faith. They wonder if Atheists are really right and they are wrong. They try to solve this problem by rejecting Atheists. If they could they would kill us.
I agree. I do think we represent their own doubt.
Looks like it actually uploaded the whole video instead of showing the link...well that's convenient.
