Anewmorning gave an awesome explanation of polygamy vs adultery. If there is one thing that I really can't stand, it's blatant ignorance. I have read so many rants on the Mormon church on this site, but everyone with a problem usually has no first hand experience, and is only going on with the 'Newschooler's teenage status quo', and saying things that have nothing to do with Mormon beliefs. If anybody really wants to know about our church, ask someone who is a member... don't believe hearsay.
Furthermore, let people believe how they see fit, instead of talking heat on their church. A Mormon is not 'better' than a Catholic, or a Jew. We believe to be part of the only true church on the Earth, but many Catholics believe the same thing. It all comes down to doing what makes you and your family truly happy.
Dance, magic dance!
