well, I know this is bringing up a rather long-dead conversation, but I'm relatively new to the sight, was idly flipping through debate forums and found this one.... sorry, but I felt I had to jump in. If you all are still around, hope you see this, 'cuz its important.
One of my best friends is "mormon". Mormon is basically the common name for members of the Church of Jesus Christ of Latter-Day Saints. They're a Christian denomination, and they aren't polytheistic. They also have no issues "owning up" to it, because there's nothing to "own up" to. Their faith centers around both the Bible and the Book of Mormon; I'm no expert on the subject, but I'll dig out what my friend told me and see if I can explain this well enough.
Basically, the LDS church was founded when Joseph Smith found (or was told of by vision of an angel, or something like that, as the church believes) the golden plates on which was written, essentially, the history of the Americas which later became the Book of Mormon. This history is much like the Bible, in that it tells of the various conflicts amongst the tribes, individual stories of prominent figures, miracles, and the hand of God in it all.
Also, part of their scriptures include the Doctrine and Covenants, which is the book of scripture that contains the revelations from God to Joseph Smith and other latter-day prophets. Their church's president is also believed to be a prophet, and they also have the apostles, one among whom becomes the next president/prophet after the current one dies.

So, even though I know it wasn't on the original topic of this thread, I had to say something, because I literally wanted to bang my head against my desk repeatedly when I read the comment about polytheism... no offense meant.
But, the LDS church is one of the fastest growing and most rapidly expanding church in the world right now... better keep up with current events!

One thing to keep in mind, however, is that the LDS church suffered a lot of undue persecution, and during a trek across the nation to Utah many of them died or were killed. Their first president was murdered, and by those who called themselves good christians. All of it was in the name of God and truth, I'm sure. So if you ever do hear more about the LDS church, and it's either derogatory or it makes them sound like evil atheists or something, don't believe it until you look up the history of the church itself. Also keep in mind that every denomination which has split from the original followers of Christ has suffered persecution of some sort by those they broke from. Technically, so did Jesus himself when he broke from the Jews. Whatever you believe, don't trust what you hear unless you can form your own opinion based on unbiased information... in other words, someone who isn't of the church but will present the beliefs thereof, for the simple reason that like all others, they need to be presented. *cough and I'm not from their church cough*

So.... that was my speech for the day (night? it's like 1 am here) so I'm gonna leave it at that and hope one of you happen to come back to find it, and get some of those questions answered.
