Mormons actually are divided. In order to become part of the US and not be chased out by the Cavalry, they had to accept the Constitution and give up certain practices (such as polygamy and child marriage) that they had cultivated up to that time.
However, not all of them did so, which is why you have these weirdo cults living on welfare out in the desert.
I think there are some of the “adapted” Mormons who genuinely want to be Christians, and they should go off and find a good Evangelical church somewhere where they might fit in and abandon their crazy cult.
The same with Muslims. If we had been strong enough, we could have made them accept the Constitution and settle down. While for years Muslims living here did do just that, in recent years, with their 9/11 victory, they have switched their allegiance and now Islam, which is a rival political system, is not only reviving in its most vicious form, but will probably take over (even though they represent only about 3% of the population).
This is because we have a Muslim president, a corrupt and foolish press, and a left that hates the West and will do anything to undermine Judeo-Christian culture.

The LDS are Christians and don’t need you or any other permission when none of you have been annoited by the Lord Jesus Christ!
