That's a hagiographic way of viewing Mormon (specifically, Brighamite) history, given they brought the vast majority of their calamities upon themselves (especially in the early days). Be it from a womanizing, ephebophilic founder who speculated with the financial fortunes of early members in Ohio, to disregarding pluralism on the frontier in their establishment of hegemony, to declaring himself a God after being a priest and a king with the second anointing, to the establishment of a theocracy in Utah and partial theocracy in Illinois, to the usurping of civil law for ecclesiastical law up into the 1900s, to the exercise of polygamy, to the persecution and targeting of established religions, to ongoing racist and sexist cultural philosophies and doctrines, to the hoarding of wealth, to paying tens of thousands of dollars for rugs, to the economic favoring of corporate leaders (e.g multiple homes for their leaders) and family (ever wonder who puts in the curtain dividers) there have been many, shall we say, missteps.

Fortunately for Mormons who remain in the Brighamite branch, there are several counterfactual examples of where their religion can go, not the least of which is the branch housed in the Community of Christ, which has followed a much more ecumenical path and openly confronted the history that was hidden for a long time.
