A lot of cowboy and Western novels mention once in a while how people shouldn't travel too far out into certain "Mormon territory" lest they get "hunted down and slaughtered by those folk." The Mormon Meadow Massacres of 1857 were considered the most hideous example of the cost of human life by religious fanaticism on American soil until the attacks on 9/11.
My father's second wife was an exMormon and as a boy I got to hear stories all about the Mormon Massacres and even about the Mormon Witches!
Mormons had their own period of "fear of witches" among them and had trials so ghastly that much of it is pretty much deeply hidden. However there are people who, out of protest and rebellion within the culture, to defy and remember the innocent blood spilled, steal Mormon temple garments and practice "Mormon curses" upon LDS church members--or so my step mother told me, and do so often circling LDS homes at night (or at least once did so in the past). Her ex-husband belonged to such a priesthood/coven at one time.
There's a lot of weird Mormon history.
