If you really want to get technical Mormonism isn't nearly as strict and crazy as everyone thinks it is. It's less strict than say, Islam or Judiasm. Essentially the Mormon requirements boiled down to this: No exo-maritail sex, don't abuse drugs, don't drink coffee or tea, pay tithing, believe in the religion. However, a lot of other things are required to fit within the socially hiearchy, which varies a bit depending on where someone lives, Utah Mormons are the most conservative. Technically Mormons can marry outside of the religion, but they cannot be "sealed", and it is frowned upon within the church.
