"but the way you Americans trivialise a toy good for nothing but war in many cases"

Ever heard of hunters? A LOT of people hunt. Also, until relatively recently it was common for american kids to bring guns to schools, and leave them in their car until after school so they could go hunting, etc. Instead of addressing things like mental health issues, it's easier to demonize guns because the politicians don't actually have to do anything other than introduce token legislation.

It's a right written in the constitution, and only referring to guns as "weapons of war" is political rhetoric. And hunting is not the only reason to own a gun- that's also political rhetoric.
