Yeah, having visited a few times I get that the media portrayal of the US being a 21st century Western is off. And I sort of get the idea that "people are much less likely to start anything if they know most people are carrying". But there's a tacit assumption in there that criminals have guns. For all that legal owners may not be a problem in the vast majority of cases, the more firearms there are, the bigger the pool of firearms there are for criminals to get their hands on. Having read through a few of these responses it seems to boil down to how much US citizens trust their government compared to other countries. The fact that there are federal bodies - such as the army - with enough firepower to flatten a city, yet people insist on carrying guns because they don't trust the government feels a bit off. But I think I'm straying from your point there.
I don't want to go further down a tangent here, but you also see how little Americans trust their government in the number of people reluctant to get vaccinated and the number of people who seriously believe the election was stolen. Both of those examples are mostly right leaning people. But this is also the same group that's most interested in gun rights. Is there similar distrust for the government on the left, if so how does it present? What irrational behaviours do democrats have because they distrust their government - or is distrust of the government mostly focused in the right of the political spectrum?
