I don't think you've summarized David's case correctly. David has shown how logically clear thinking substantially diminishes the chance that Christianity is correct. This is not based on his opinions; rather his opinions are based on this logic.

On point 2, one thing I tried to point out in my two long posts on Christianity a while back, is that different people's religious beliefs throughout the world show a logical consistency with the circumstances of their geography, history, existence, and method of subsistence. This shows me that it is much more likely that their god was a result of their existence rather than the other way around.
