I consider Mormons to be average people.
I'd say both. It's a mixture.

Many of the morals in Twilight are not ones that normal people follow by. Very few of the things in Twilight reflect real life, but I suppose that is just another attraction for Meyer's girl fans. I cannot say that the books flood with Meyer's religion, but there is quite a handful of her beliefs. Obviously the morals cannot all be Meyer's or else the books will slide downhill even faster. There is a combination of both.

I don't think so, but then I'm not sure which morals you're referring to. It's interesting to note that a lot if not most Mormon's morals coincide with other major religions'

Mormon's are people

I feel bad for saying this but I always feel like Stephenie was trying to pawn her religion off through Bella and Edward's waiting to have sex till marriage. I like Stephenie as a person, but I don't know ...

Um, I didn't see many distinctly "Mormon" ideas at all. A lot of her ideas were general Christian ones.
