It is true most Christians have no idea. We have seen it a lot on here, people come in defending Mormons as nice people and “Christians” then find out what the Mormon church really believes and teaches and go ‘SAY WHAT?!?!?’
Also, it needs to be pointed out that the Mormon missionaries FLAT OUT LIE about Mormon teaches to potential converts, so you hear one set of things and teachings before you join and once you join you find out the rest of the stuff.
That is part of the reason why there is an over 50% inactivity rate among converts the first year here in the US.
No church should have to lie to either its members or the outside world - one more proof they are a cult.
I have no idea what the Mormon church teaches BUT I did live in Idaho and knew many Mormons. They were all good people, very community oriented, helped non Mormons as often as Mormons, were great friends, parents, and neighbors. I never saw any freaky rituals or cult like activities. On the occasion a whacked out Mormon made the news for a too young wife they called for his castration as fast as I did and none of them I knew had a wife that would tolerate another woman at all.
Sadly, it appears that most Christian do not know what THEY supposedly 'believe', either!
Thus the relative ease that the salemen of MORMONism, with their apparent grasp of the 'scriptures', can lead SO many biblically illiterate folks away from the True Christ into a life of slaving away for TCOJCOLDS - The Church of JESUS CHRIST of Latter-day Saints.
