There are no rational religions. They are all based on faith, belief without proof.

Absolutely not. There is a great deal that can be learned from a rational and even scientific study of religion. Because religion has always been important to humans throughout history, it is clearly something worth analyzing. In fact, supporters of religion often make more sensible arguments than its critics.
