What do Mormons teach that makes 99% of Christianity consider them a cult?

This is why I say it is from satan and the people are being deceived.

[Mormon McDucky]

""No salvation without accepting Joseph Smith...No man can reject that testimony without incurring the most dreadful of consequences..."
-- If you want to get technical, we believe you have to accept the Gospel to go to Heaven. Which inadvertantly means you must accept Joseph Smith (and Moses and Abraham and Elijah and all the others for that matter) was a Prophet. I imagine that was what was supposed to be implied when the person said that.

""In our marriage relations here we are marrying our brothers, and our sisters."
-- Oooooh my gosh. You are taking that way out of context. In our religion, we call each other "Brother" and "Sister". That's what Brigham Young was talking about, silly. He wasn't referring to literal flesh and bone brothers and sisters.

""...the protestant churches, the harlot daughters which broke off from the great and abominable church,(The Catholic Church)..."
-- Hahahahahahhahahahahahaha!!!!!!!! This is coming from the guy who spends so much time bashing and criticizing the Mormon church. I lov the hypocrisy. You think that *you* have the right to say whatever you want about us-- but if a Mormon dares to say anything against *your* church HEAVEN FORBID! Oh, the irony of it all...
