It’s weird because Switzerland is one of the most armed countries in Europe, as in they have firearms but barely any shootings of any kind (so you don’t often hear news equivalent to a guy shooting students in a classroom or killing people at a shopping mall over there). Part of it has to do with the draft (most people who purchase firearms have a form of training, as they learnt how to properly handle them during military service).
You got part of it. The Swiss get formal training during their military service, and understand that owning a gun is a responsibility and an obligation, not a right. They have a sense of duty around their ownership.
But another big part is that nobody on the planet fetishizes guns like the US. Guns are a symbol of virility, of sexual prowess, of “American Freedom.” Facebook recently showed me a reel by a woman who poses (nude) on OnlyFans with guns and motorcycles. That is a profoundly US mindset. (And of course the guns are assault rifles.)
Only in the US and a few other pockets of rednecks are guns fetishized.
You missed the countries those rednecks ironically hate, because they share so much. They both want to impose their version of religious law, both fetishize guns, both hate women, and both have some serious problems with closeted POS.
This always annoys me about the US. A gun is a tool. There is nothing inherently political about owning one. I own a lump hammer and a sickle but that doesn’t necessarily make me a communist. I just occasional need to bang things and chop things.
