This is how I view preparedness: EVERYONE needs to be prepared. For what? For whatever.
From a child's diaper exploding on you while shopping in Publix, to the rapist in the park, to the ice storm that cuts off power for a week, to the sudden and unexpected death of a loved one. It truly pays to be prepared, and it especially pays to surround yourself with prepared individuals. Who wants to live in a neighborhood of "entitled" snobs that chap the teat of charity with their incessant suckling, when one could be surround by hard-working individuals who know the value of honesty, grace, justice and mercy?
It's why I tell everyone to be prepared for anything (within reason). Job loss, baby poo-splosion, and power outages? Definitely have those! Zombie apocalypse, earth-scorching solar flares, and alien invasions? Not nearly as likely.
I think that if we become the "secret squirrels" that the media portrays survivalists as, then keep it to yourself. Survivalism has enough of those; we need real men and women that genuinely care about God and country and what to do when the dirty diaper hits the fan.
