Hmm.. Well as i said I know verry little about them. Here they call themselves mormons and teach, from what i've heard, the same kind of techings that is most common in USA..
btw, I've seen several docementarys about polygamy that featured mormons and their many wives, so it is still practiced even though the mainstream "mormon"-churches doesn't allow it.
Anyway, I assume that the reason they didn't allow me to study their religion was because when i asked i had a t-shirt thait said, "Ateist? Javisst!", witch means "Atheist? Ofcourse!", only in swedish it rhymes...
