I'm not a Mormon and I don't deny that I think the particulars of their belief system are often weird. But I don't think the nature of Mormons actually matters in this context, and speaking generally I don't think there is anything wrong with people choosing which media they and their families consume. If people want to fast forward over parts of a movie they don't like, I think that's understandable. And if their decision about which parts of a movie to skip is weird to me, so what?
