What exactly is the source of the USA far right/gun nuts paranoia and longing for weapons?
I recommend to read this article by Rick Perlstein
in which he skewers the source of the right wing paranoia.
The concise version is, "follow the money, stupid". The right wing media machine, from Fox News down, is a massive money extraction mechanism that emits terrifying sound-bursts then offers to make the problem Go Away For Just $25 A Year.
The far right/gun nuts sure are soft targets for propaganda.
