mromons believe everyone is a god, and that God the Father is the son of another god, who is the son of another god, etc. etc. etc. that Jesus & Satan are brothers, born to the Father & His goddess wife on planet Kolob, where they used to be human but eventually through enlightenment or something became gods.
that Satan's plan was predestination but Jesus' was free will, so the Father decided He like Jesus idea better, and made Satan play bad guy so it would work out.
they believe women will only be resurrected if they marry and their husband calls them by name after he is resurrected - so it's up to the whim of men to decide whether or not women can have eternal life.
they believe that the only way anyone will ever go to hell is to be a mormon and then quit the mormon church. everyone else, no matter how you live your life or what you believe, will go to one level of heaven or another.
they believe that the afterlife consists of men constantly procreating to populate other planets with people who will grow up to be gods of their own planets, and women's purpose is primarily just to have these babies.
their missionaries won't tell you these things - most of them probably don't even know it, because they send people out to be missionaries while they are still young and not fully indoctrinated. but this is what the people they call prophets say, and they believe those people speak directly for God. there are a lot of things no one will tell you about mormonism until you're in too deep to get out. they pretty it up and make it sound like Christianity to get new converts, and quickly turn them into missionaries, but underneath it all, it's insidious and absurd.
