Some people are just paranoid and feel the need to be armed.
Yep idiots. In a normal country wouldn’t be allowed to own a deadly weapon. Maybe I am pushing it a bit too far because all other countries have hunters and a tiny fraction of the population with a good reason to own a firearm, but gun owners are idiots is a food enough approximation.
Also, you can store a nuclear weapon safely in a house doesn’t mean any idiot should have one.
