Ha. I, too, was introduced to The Golden Compass by the American Catholic League trying to ban the movie or at least complaining about it a lot. God bless 'em, as I now love those books.
But considering that you and I are already avid readers (or at least I imagine you are, being on mobile read), I think we may not be a representative sample. The fact that it's a draw for a Heavy Reader would make me think even more that it would be a myth that Moderate and Low Readers bee line to banned book.
