The issue of gun ownership is cultural more than anything.
In Murica, we believe in personal responsibility and embrace a healthy skepticism that our gov't and/or military will always have our best interests as their primary goal.
Political overthrows are messy, and we are lucky to live in countries which haven't gone through serious periods of lawlessness or self-aggression. Plenty of examples of people living today are not so lucky as we are. Our countries may not be so lucky in the future. It's naive to pretend that vesting your safety in other people is an effective long-term plan for your safety. Your safety ends when those who are supposed to protect you decide to turn against you. Sure, that doesn't look likely in our current political environments, but that doesn't mean that it wont ever be likely.
If a person who doesn't want to kill people owns a gun, they are not threat to me or other people. If a person wants to kill people and doesn't own a gun, they are still a threat to me and other people. The gun is just one of many tools that person may use, but it's not the gun I'm afraid of, it's the murderous intent.
The outrage at guns causing death is absurd.
