I can agree with the obsession part....been watching it on here and other places for some time now and I'm just as mystified. When we are given links to sites that promote sneaking supplies into your house under cover of darkness so the neighbors can't see what you have, etc., it gets to feeling a little obsessive.
Back in the day, being prepared was just life and no one had to form a plan of stocking up, prepping, etc. and have discussions about zombies(pathetic), SHTF(WITW?), or any other such nonsense. It has become a new fad and even the subject of tv shows, books, forums, etc.
Out here in our neck of the woods, getting prepared for actual living means growing and storing foods, having supplies on hand at all times for power outages and systems in place that make living easy when the power is out for any length of time. Here it is just wise to do this and nothing of which we discuss at length...it's rather taken for granted that smart folks lay in food, firewood, fuels and such for winter and for the year ahead. No feces hitting the fans should need to be in the offing to practice common sense living.
People got away from that and now think it's a new and shiny thing to jump on the wagon of prepping for this or that emergency....the very same emergencies that have been here with us throughout the history of the Earth.
Why don't folks just call it what it is....it's normal, practical, logical life practices that keep a person prepared for emergencies as a matter of course. It's not for any scenario other than the human condition on a planet that has natural weather changes that cause us problems at times. Nothing new, nothing to write volumes over...it's just life on this planet. Get over it already.
