This evening, I sat and watched the show for the first time. One of the families was a prepper group that was preparing for a New Madrid earthquake event. They were pretty well set up with food, farming, honey bees, and a decent skill set. They had a prepper community of about 30 people in the area that traded skills and supplies. There was one main flaw in their preparations: security.
They claimed that they ethically did not want to have guns and ammunition like the "right wingers" and said that their main security was being part of a nurturing, friendly community of people who would support each other. They said that should a marauding band of armed people come to take their stuff, they would feed them and offer to trade with them. If that failed, they claim that they will poison the attackers with the food supply, or cut their throats while they sleep.
That tells me that it is not an ethical issue about violence, but a fear of inanimate objects. It also tells me that since they have no way of protecting their food and supplies, they will not keep them for very long.
I also concluded that the preppers in this show make the prepping community look like a bunch of idiots. From the 400 pound guy running around his yard with a rifle, to the family that was building a bunker to defend against a world wide tornado swarm, this show make preppers look like a bunch of loons. Maybe that is because the first rule of prepping is to keep a low profile, and the only preppers who would go on such a show are the dumb ones.
