But, those are hardly just Mormon beliefs. Those are traditional constructs and social values of the binary gender system. Sure, they are pretty sexist and restrictive in practice but they are not just religious values the Mormon church embraces. I think the series is a lame attempt at celibacy rather than someone trying to equate Mormon life through vampirism.
You're right, of course. They're NOT just typical Mormon beliefs, but the thing is, Mrs/Ms. Meyer IS Mormon, she's also a big fan of abstinence and celibacy AND she's outspoken and devout about her religion. Whether or not those 'values' are shared among other belief systems doesn't matter here. What matters is the writer's intentions. And as a devout Mormon, her beliefs got in the way of her writing.
Now, here's the thing, and I'm pretty sure I'm going to offend someone, and that I sincerely apologize but that is not my intention. However, the problem is that the Mormon belief system is rather anti-feminist, with a lot of it does promote unhealthy romantic relationships because of how they interpret their holy books. Thing is there are some Christian and Catholic sects that promote more egalitarian beliefs, not to mention other religions that do the same. The real issue is 'Humans', we tend to twist or misinterpret topics to suit our wants and needs, sometimes to unhealthy levels.
The fact of the matter is that most of the archetypes that Ms/Mrs. Meyer used are so one dimensional and clearly offensive on so many levels.
