"No self-respecting bona fide atheist ever expresses certainty about God's non-existence".

Rather dubious, but let's go with it.

So, since that is the case, let's hear all the professed atheists on this thread admit publicly and individually that there is a chance God exists.

This should be entertaining.

And then you can tell us how you pledge to to refrain from attacking the beliefs of those who differ from your attitudes towards religion.   Since after all you have just admitted that the difference between your belief in God and their belief is a just a matter of degree. And there is a chance that they may be right and you may be wrong.

I'm sure that, being reasonable and civilized people, you have no problem in any of this.

However, I will not be holding my breath.

The statement which comprises the title of this immensely worthwhile and informative thread has been proven beyond doubt by our wonderful contributors.
