Re: I'll never understand Americans and their fetish for guns
It's not all Americans though. Only about one third of people in the US own a gun, but most of those people own multiple guns. They're a very vocal minority (and I mean vocal in the US sense of "giving lots of money to a lobbying organisation").
And personally I can see some of the attraction. As precisely made (or not, a lot of guns seem to be terribly manufactured) mechanical devices, with interesting engineering decisions, they have a geeky appeal to me, in much the same way old cars, or teletype machines, or mainframes, or aircraft do.
A Spitfire is as much a machine designed for killing as an AR-15 is, and there's no shortage of people wanting to see a Spit.
