There’s a whole bunch of guys out there (mostly guys, a few butch girls here and there) who sulk online for years waiting for somebody to bring up the Omega Man/I Am Legend scenario: what are you going to do when civilization collapses?
It usually comes down to gun talk. That really makes me laugh. As if small arms would get you through the end of the world. Oh, I get the idea. In fact there was this joke when I was in high school that summed it up nice: “Q: What is the definition of a survivalist? A: Somebody with a rifle and the address of a Mormon.” Because everybody knew those Mormons were required by an official memo straight from God to Joseph E. Smith, Jr. to stockpile canned goods for a year in their tidy little basements. If you had a rifle, the idea was, you just strolled over to their house and either ordered them out if you were feeling all interfaith-cuddly or shot the whole bunch, although with those Mormon birth rates you’d be using up a lot of ammo on basically harmless people.
Well, they were harmless back then. I suspect if you kicked down the door of the average Mormon house now you’d get a face full of buckshot. People are meaner than they used to be.
