The US has a gun ownership ratio of 101 guns for every 100 citizens
they can arm every man, woman, and infant in the country
that's 3-4 times more than any other first world nation, and twice that of countries in active war zones
2nd amendment has existed since 1776, while the gun ownership was comparatively low until post Vietnam when a generation of US men was taught to be killers and that their gun would protect them from everything
Americans insist they needed his, so why does the rest of the world, including places where gangs and militias run wild, survive just fine with far less of them
