I've talked to people about prepping and a lot say they want too, but don't because they don't want to be looked at or labeled a conspiracy or tin foil hat nut.
The brainwashing has been effective but I'm also glad to see that most are still concerned. At least that means they are paying attention and thinking about it.
My answer, to them, who cares what somebody else thinks and if you need an excuse blame it on hurricanes, earthquakes, tornadoes or natural disasters. What ever makes you feel better as long as you're prepared to take care of and defend yourself and family.
