OK, Mormons (or, as they'd probabl;y describe themselves, members of the Church of Jesus Christ and the Latter Day Saints), have their views based on the Bible (of course) and also on specific texts, including the Book of Mormon.
Two very nice lads used to come round my place the whole time to try and 'convert' me n the missus
So, when they're around 18, the apply to "central office" in Salt Lake City, and are assigned a place to go in the world (could be in the next city, or in another continent where you don't speak the language). You are paired up with a stranger, and you have to live with them on a tiny amount of money – if you spend it all on the first day of the month, you starve for the remainder).
The idea is that this missionary work (they are required to go out and try to engage people) allows people to grow up in the big wide world. It's tough – you get to make two phonecalls a year, and you don't go home.
The polygamy thing apparently had a history in times when communities were persecuted, and the men killed. So, a remaining man would take responsibility for widows and their children. This was trhen skewed by people who wanted several wives. It is frowned upon by the mainstream Church.
They don't drink alkyhol, caffeinated drinks or smoke tobacco.
Mormons don't drink or smoke, that's correct. Some are very observant of the non-caffeine consumption, but the reason they don't drink tea and coffee is not the caffeine content, but because the "health rules" forbid them from consuming hot drinks. So, no hot chocolate, fruit tea or whatever.
We're all (mostly) normal. But then what would you expect from the people who "invented" Moab.
How am I doing Spamf? I gleaned much of this info from a chap I shared an office with at work, though it's been a while and I'm sure it's littered with errors.
He was the life and soul of every party, and the father of six sons (all with Old Testament names – though I never could convince him to name any of the last three after Methusela…).
I have to say that he was, like so many people with strong religious convictions, outwardly perfectly normal. I can't say I can agree with all of his beliefs, and I dare say he didn't agree with mine (agnostic, living in sin, etc.). But we got on just fine.
