I wish I could vote you up so much more! The distinction between a-convincing-argument and what-it-would-take-to-convince-me is very real and overlooked by almost everyone posting here.
To take my own experience in becoming convinced of atheism, I sometimes like to think I accept atheism for the same reason that I accept evolution—because of the evidence/lack thereof/etcetera. But that is simply not the case. I accept atheism because of a highly personal history of what it took to get me, personally, to stop believing in Christianity, and start believing in something else that, as much as I would like to pat my rational self on the back, has fairly little to do with the arguments and evidence I heard on the matter.
When asking someone why they believe something or are convinced of it, “what is the reason?” and “what is your reason?” are two totally different questions.
