Why do Christians as a community seem so incurious about atheist arguments about Christianity?
Why can't I find any prominent Christians who are conversant in sociobiology or know the specifics of the Randi million dollar challenge?
Are atheists not doing a good enough job of promoting their arguments?
Are Christians scared of what they'll discover if they start learning atheist material?
Are the two sides simply operating off mutually incompatible mental frameworks?
Or am I off base and these Christians do exist and I'm simply unaware of them.

Regardless of your beliefs, I believe it's basic intellectual integrity to be aware of the best arguments from the other side and I think Christianity as a institution has failed in this task.

(not to pick on Christians. If anything, I think Muslims are even more incurious).
