Man bites dog...

"Be careful. People like to be told what they already know. Remember that. They get uncomfortable when you tell them new things. New things... well, new things aren't what they expect. They like to know that, say, a dog will bite a man. That is what dogs do. They don't want to know that man bites dog, because the world is not supposed to happen like that. In short, what people think they want is news, but what they really crave is olds . . . Not news but olds, telling people that what they think they already know is true. "


—Terry Pratchett, through the character Lord Vetinari from his "The Truth" a Novel of Disworld.


This might help explain why so many people can become offended by alternate theologies.
