Drinky once said something about most Mormons approaching their religion like a souped-up, community-oriented Christianity, and that sounds right to me.
My personal experience with Mormons (none of whom were from Utah, AFAIK) was that they tended to be a lot more positive generally, as well as less insular or disdainful of outsiders.
Maybe it's that the people who converted were attracted to the idea of building a community, rather than seeing themselves as the righteous heirs of a tradition that's come under fire from all directions.
edit: Yes, FoC, you eat shit because you say incredibly ignorant things, but people don't accuse you of secretly being Muslim.
