While the interpretations of the Batmanical scholars may seem at odds with the text, any contradictions you see are a result of your own imperfections. Do not be tempted by the Joker into doubting the word of Batman. Unbelievers are a superstitious, cowardly lot.
Personally, I find it amazing that a work with such a diverse spectrum of writers can survive for so many years, and maintain its consistency so strongly.
