Mormons have a year or two of supplies stored as a matter of practise.Its a community rule.No one calls them horders! I think they are damned smart!
These urban yuppie "preppers" who've accumulated a couple months supply of food, and are embarressed, lest anybody think that they are survivalists -- they are simply hoarding food, a common practice amongst a certain population of clinically OCD.
Mormonism has nothing to do with OCD, and certainly most reasonable aedults would NOT be embarressed to be referred to as a "survivalist."
