Genealogy is a passion of mine, so I am grateful to the Mormons for all their archiving and record-keeping, but when I used to visit an LDS library, it was clear to me from what I observed that it is indeed a cult. My theory is that Joseph Smith was basically schizophrenic and suffered from hallucinations, but somehow a huge religion came out of that, and it continues. I suspect that somewhere deep in the LDS organization, a few people are making lots of money.
I have come across forums and website for excommunicated (or disfellowshipped?) Mormons. I don't have any links right now but I recall seeing a very supportive community. I have a friend whose whole family was shunned by the Jehovah's Witnesses, and she had to go through some deprogramming, too.
The world opens up... when you do.
