I support the "Red Jacket" standard for religion. By any standard, all other religions are false, so we would separate into quarreling factions. The measure of a religion is whether its origin is true, false, or hidden in the depths of time. It's measure is the behavior of its current day adherents.
"Brother, we are told that you have been preaching to the white people in this place. These people are our neighbors; we are acquainted with them; we will wait, a little while and see what effect your preaching has upon them. If we find it does them good, makes them honest and less disposed to cheat Indians, we will then consider again what you have said."

By that standard, the Mormons do very well. You do not have to believe their religion, nor to believe in the faith of the Muslims, Jews, Baptists, or Catholics. Just note the virtue in the modern practioners.
About the same time the Joseph Smith Jr. was born, a variation of Islam grew out of the desert, that rejected all knowledge that was not contained in the Koran or hadith. I would seek my allies among the followers of Joseph Smith Jr, rather than among the followers of the Wahabi.
"Just note the virtue in the modern practioners. "
That would be the problem.
Wahabi So when do you expect the mormons to blow up buildingZ?
