Dinner with 2 Mormons

Ryan and I had dinner with 2 young mormons the other day. We didn't talk theology at all, just daily life, living in Japan, difference in schedules, plans after Japan, etc.
I was surprised at how much the headquarters controlled their lives. Basically for 2 years, they do nothing but walk around the city, talking to people. No internet, no caffeine, no phone calls to home (except twice a year on Mother's Day and Christmas), no email, one letter per week, no potentially dangerous sports, no music except church music, 9:00 curfew. Every six weeks (maybe it was 12) they will get a call telling them whether they will move to a new city or stay in the same city. So this basically precludes relationships from forming.
Two things should be said about mormons:
1) They are usually nice people, people you'd want as a neighbor, generally sincere in their belief.
2) They have terrible beliefs:

-Where the Book of Mormon disagrees with the Bible, the Bible is in error because of various translation problems, although Joseph Smith had no problem plagiarizing thousands of verses directly from the 17th century King James Version, and claiming they were from documents over 1500 years old.

-Until recently, the past 'presidents' of the mormon church taught that Blacks could not be saved. After all, they were too sinful, and were cursed with black skin. Thank God they retracted this teaching (even though the 'presidents' are said to be infallibly authoritative).

-The god of our planet used to be a man on another planet, and he was so virtuous in that life, that it was granted to him to populate Earth and become its god. And now all perfectly virtuous mormon men on this planet will become the god of another planet, which they will populate with their many wives.

And how many people are currently suckered into this crap? Would you believe 12 million? I want to talk theology next time we meet the mormons for dinner.
