Different main themes and central ideas in Ray Bradbury's Fahrenheit 451.

I think many english teachers cannot grasp the fact that there are different ways that books and stories can be interpreted. I am right now writing my summative essay for Ray Bradbury's Fahrenheit 451 and I am struggling with writing arguments for the distinguished main theme of censorship while I saw the main theme to be distraction. If anyone has any good pointers please tell me.

Sorry for bad english.
