Disagree. I’m not from the US, so maybe guns being seen as fun is more of a cultural issue in not aware of, but plenty of weapons are seen as fun here in the UK. And while we do have gun crime, I think firearms are seen differently here vs the US.

People will go axe throwing for fun. With Scouts, we shot air rifles on camp a number of times (supervised by people who knew what they were doing). Knife throwing is also a thing. Clay Pigeon shooting is also not uncommon here.

I genuinely believe using a weapon on a (non-living) target is fun for a lot of normal, well adjusted people.
