The real problem is that these people live in a world of fantasy and prep for the zombie apocalypse. It's this quasi sexual thing where they get a hard on for shooting everyone that moves, without guilt of any kind.

The problem with their approach is that the zombie apocalypse won't happen and the people with guns are likely to be the ones starting the problem when things go slightly bad.

BTW, I have lived through natural catastrophes where we got isolated and without power for many days. Curiously, neighbors got together and helped each other. No rapists or crazy marauders. Sadly, everybody went back to their natural state of isolation once the crisis was averted.
