I don't read polemicists either of the religious variety or of the atheist variety.I think this is where you misunderstand atheism. You keep pointing to Dawkins, but Dawkins isn't all atheists. He's just one of the few who actually writes about what some think. And good on him. We've enjoyed two millennia of people forcing Christianity into every nook and cranny of our society, so at least give us a couple of people who say "The emperor has no clothes".
Polemicists aren't convincing to me.
Christopher Hitchens and Richard Dawkins are mudslingers who have adopted a belligerent style to sell books, but their criticisms of religion is ultimately superficial and unconvincing.
I will never read anything from Joel Osteen or the Creation Science Museum Research Institute. Unless I need a laugh.
The most rational and compelling arguments for Christianity I've read are from the Oxford scholar CS Lewis and the American geneticist Francis Collins.
The most rational arguments for a non-relgious tradition I've read about are from Albert Einstein and the existentialist Albert Camus.
