It's not harmless, this prepper stuff. It almost always involves guns, guns, guns, conspiracy theories, a distrust of government and society, and huge doses of paranoia. Which wouldn't be such a bad thing if they weren't actively poisoning the minds of other gullible folks. "See them thar chemical trails off of that airplane, sonny?" "That's the gubmint trying to kill you".
You sound just like these people you are slagging down
Preppers have nothing to do with the people you are talking about. Preppers in the US are almost entirely a product of hurricane Katrina. Looting of food and other essentials took place within 24 hours. This scared the shite out of a lot of Americans. Of course the reporting of looting was exaggerated, not of essentials but of electrical goods etc.
Then in the UK we had the 2011 rioting where the police at least initially, stood back and watched. This reinforced UK preper views, that they should be prepared for not just a collapse in law and order.....well in reality that is all they are preparing for. Wherever it is caused by a meteor strike or Coronavirus. The Coronavirus has resulted in a "I told you so ".
Of course the Coronavirus is hardly the same as meteor strike ie plenty of "preparation" by the authorities.
Alas most prepers are idiots who think they can load up there imaginary Bergens and just nip into the countryside and live off the land. Nobbers!
