Mormons were mostly good people. Their religion is a joke: a corporation pretending to be a religion. In the old West days, Mormonism worked because it was a farming/ranching co-operative that pretended to be a religion. It was centered around family, tribe, and townships (and pioneering those townships across the West).
In the 1950's the shift to turning into a top-down corporation occurred and local Mormon churches went from having an individual flavor and culture, to being more like sterile franchises (all teaching the same approved blandness, called "correlation"). If your Catholic, this would be like Vatican II stuff in the 60's. Same kinda "reform", but with much more tightening of control.
It didn't take long for the fruits of this to occur: acceptance of race mixing, massive efforts at demasculization, acceptance/tolerance of feminism, acceptance of gays, costs reduction over people/programs, charities frauds, birth rate drops, etc…
At this point, Mormonism is run by plastic Mitt Romney mid-level management accountant bugmen. I don't think it can survive in its present form much longer than a generation or two. I expect it to schism, possibly into two: a right wing fundy version (ID, UT, AZ, NV) and a left wing version (CA mainly with packets in major cities in UT, AZ, ID).
I would work to convert Mormon's to more sensible thinking in regards to race & white genocide. Maybe try to get them to move toward embracing faith tradition & pioneering spirit and family and leave behind the blind following of "prophets" like the first Mormon con-man Joe Smith (himself a kiddie diddler and wife swapper). They can't do this openly very easily or they will be kicked out the door. Although more and more are walking away anyway.
Many Mormons can be reached, especially the younger ones. The boomer aged Mormon's are hopeless and are basically the definition of neo-con cuckservative.
Looking for some sort of group of like-minded people to join is bound to disappoint. While you will have the best luck in rural areas, note that Mormon's won't fight or rebel against the POZ until they get out from under their current do-nothing leadership and realize that their POZ worshiping religion is a crock of lies.
When you believe that American Aboriginal's are literal decendents of gawds chosen people da jews, it is really going to be hard to address the jew question. Another downside: they are wearing magic underwear and selling multi-level conjob crap like Amway, while giving 10% of their total gross income away without question– so they are overall very gullible. In cities, they are very egotistical, vain, and money driven. The rural communities are were you find gold. They are family driven and don't like what they see coming out of Salt Lake/Washington/etc. They still haven't put two & two together to figure out (((who))) is pulling most of the strings, but they are at least good and pissed and willing to fight (think Bundy Ranch).
