Earlier quoted context omitted.
As with many religions, "tolerance" is a sensitive issue: blacks, women, LGBT. But yes, there is the stereotype of a humble/reserved successful Mormon businessman. (E.g. I'd put Mitt Romney in that category too)
Not many religions in the U.S. have tolerance issues with "blacks" or "women", per se. The LDS church was unique in that regard. But to be fair, that aspect seems to have been sincerely discarded. What lingers is the uncomfortable landscape it finds itself in, and given the background racial landscape in the U.S., I'm sure it'll be an especially long journey out of that wilderness.
But if you're comparing it to churches that have been around only 10, 30, or 50 years, sure.

It used to be that the LDS Church was "too" pro-black by society's standards.
That was a large reason for Missouri's infamous Mormon "Extermination Order":
> We believed them deluded fanatics, or weak and designing knaves, and that they and their pretensions would soon pass away; but in this we were deceived...In a late number of the Star [the Mormon newspaper], published in Independence by the leaders of the sect, there is an article inviting free Negroes and mulattoes from other states to become "Mormons," and remove and settle among us. This exhibits them in still more odious colors...the introduction of such a caste among us would corrupt our blacks, and instigate them to bloodshed.

Yes somehow, very few discussions of Missouri immediately turn to its history of racism.
