Funny, I had a conversation on FR just yesterday with a Lutheran minister, and he pointed out that the flaw in Calvinism is its reliance on humanly limited reason in building the doctrine of double predestination.
I agree on your main point. That is why I think that we won't see conversions to Christianity in any great numbers, but we do see acceptance of Western practices that are a consequence of Christianity: free thinking, tolerance of diversity, bourgeois work ethic, tolerance of small vice.

I would think the opposite would be the case. I think the unreasonableness of the doctrine explains its unpopularity. Unaided reason tells us that God is Good. Therefore, it would be impossible for Him to will damnation for some people from all eternity, particularly without regard to their actions and decisions for or against God.
