Yeah, and anal about collecting tithes. This site from ex-Mormons is pretty instructive -

Most Mormons I've met and worked with are really nice folks as long as you make a good first impression. I used to train in SLC. and would take my diamond stud out on day 1, then put it in on day 2 and see how they reacted for shits and grins. It befuddled them a bit, but they tended to go on first impressions. They really are not much different from serious believers of any other magical thinking religion except that they are fundamentalist and super fundamentalists. Perhaps because they were horribly discriminated against for a century, they are a little more forgiving than most other fundamentalists but there are not really any "moderate" Mormons in terms of literal interpretation.
I'm bad because I always forget the second "m", but then that is my opinion of pretty much all religions except perhaps Taoism and possibly Buddhism. Then there is Pastafarianism!
