I just don't think they are the answer to every ( or even most) confrontations. Years of traveling ( without a firearm) the world over has shown me that you need not fear the world. People, wild animals all can be dealt with without bullets
I don't think guns are the answer to most confrontations; the ideal world would be one where differences and confrontations are settled peacefully....but I think we can all agree that isn't realistic, especially given human nature. I can tell you from personal experience, that there are many parts outside of the US, where the person with the gun is the one who dictates how the confrontation will be resolved....and the person without the gun is the one getting the raw end of that stick.
I've found that there are many areas in the world where you can travel with a reasonable amount of safety and confidence so long as you use common sense. But there are some areas in the world where I wouldn't go unless I had a full-strength infantry battalion with air support on call at my back. The context of the situation matters...
As for all that junk you were saying about people who carry firearms having insecurities...the stereotyping aside, I think you owe it to yourself to talk to people with views different from your own. Most of the gun-owners I know don't care about the political infighting associated with gun-ownership; they don't care about proving their manliness; they want nothing to do with a fight...they simply want to live their lives without being bothered. Owning and carrying a firearm in the US is a right, not a hobby, not a past-time or a symbol. I think that aspect of US gun-ownership evades most people from other countries, as most other countries never have and never intend to give that
right to their citizens...hence why places like Australia and UK, while democracies, have been able to severely restrict gun ownership to the point where most of the population was disarmed.
