Sure, engaging in violence and threatening each other's lives in public is a so much safer and better solution.
Thats a juvenile approach at best, and I would hope you understood that before posting.
Firearm ownership/carrying are not violent acts. Nor are they indicative of violent behaviors. It's merely a preparedness akin to a boxer's training. Some believe you should be prepared for the situation you are entering.
When faced with violence, bodily injury or seizure of personal property, some of us simply opt to stand ground. It isn't about being violent, it's about not letting that violence happen to me.
