I think that the fundamental point of the discussion here is that religious beliefs fall into a category that cannot be directly criticised. You can state your disagreement with said beliefs. But all the arguing in the world that there is no God is not going to convince the theist, and all the argument in the world that there IS a God will not convince the atheist.
One cannot argue with another person's belief in the Bible (in my case, the Jewish Bible; the NT is not my book). It is beyond argumentation. A person either believes in it, or he doesn't, and if he does believe in it, he has an interpretation of it. A non-Jew cannot criticise a Jew for his belief in the Bible, as he simply has no ground to stand on. By the same token, a Jew cannot criticise the atheism of a non-Jew. We know, as Jews, what God has revealed to us. We do not know what, if anything, God has revealed to the non-Jew. So we are not in a place to criticise the beliefs or lack thereof of anyone outside our own ethno-religious community.
If I have a reading of the Bible that tells me the Earth is flat, that is my belief. It cannot be criticised, though it can be disagreed with. But to criticise it and find fault with it you would have to start from the perspective of a religious Jew, which you can't do, since you are not one. I don't know if you all get the hang of what I am saying. And perhaps I am not saying it well. But, my fundamental point, is that there can be no argument between the Jew and the Gentile (whatever the latter's religious beliefs or lack thereof) because they start from a different premise.
