NOPE!
I was born into and raised in mormonism. I personally have known mormons who were/are drunks, wife beaters, child molesters (knew one from personal experience, a high mormon priest) thieves (bad checks) and frauds.
The following link is to an article in a BYU source, a mormon university.
Affinity fraud continues to plague Utahns and Mormons
The state with the highest rate of affinity fraud is Utah, where more than 60 percent of its population belongs to the LDS Church. The FBI calculates that there were more than 4,400 victims in 2012 with a net loss of $1.4 billion. It’s not that LDS Church members and Utahns haven’t been warned. In 1982, then BYU President Jeffrey R. Holland warned students about such schemes. Warnings have appeared many times over the years in conferences and church publications with a similar theme — if it sounds to good to be true, it probably is.
NOTE: "If it sounds too good to be true"...and many people fall for the sounds good "mormons are just the "nicest people" soundbite!
Ah well, I bow to your experience. I’d still prefer a Mormon neighbor to an Islamic or Son of Obama, though.
