I have seen one Mormon couple living in the apartment below me, around 2002. They were in it for about a year, and everything they did seemed to be about religion. Fortunately, they never called on me--I would have replied that I was a witless, and that would probably have been the end of the call. (Now, I would simply say that the opposite sex has a consistent history of rejecting me for no reason, and that until God FIXED the problem, there is no way I would be of any use whatsoever to the Mormon faith). They always seemed to have suits on, and they were also on the move a lot. I have seen UPS deliver lots of packages from Utah, even after they moved out (those packages were never delivered).
The Mormon faith is a little more liberal than the witlesses. Yes, they spend all their time obsessed with religion. And yes, they are always dressed up. However, from what I have heard, they do celebrate the holidays. That is less stress around Christmas time, since the Christmas songs and decorations do not bother them. They do not have to enviously watch others put up Christmas lights while they are in the dark, since they are allowed to decorate their places for Christmas (unlike the witlesses). They also allow their members to go to college, and their door to door work is limited to 2 years per person (not for life). Not that they are without quirks: They are supposed to wear a certain kind of underwear (the witlesses have not yet adopted that), and they are required to tithe. Also, they are not allowed coffee or chocolate (the witlesses are still allowed those, and will be until the Filthful and Disgraceful Slavebugger decides that coffee takes too much field circus time).
But, I would say that the Mormons are the lesser of two very evil religions. The Catholic church would be a better choice. Or, no religion would be even better.
