One thing that gets skipped over in most of these conversations, in my opinion, is the awareness and thought process that goes into (for most) carrying a firearm.
Personally, I haven't left my home without my firearm (to work, play or chores) for a long time. Not because I feel scared or insecure, but because that is how I have trained myself.
Just like any other "tool" we have at our disposal to help in a situation, having the skill set to use the tool is important. For me, once I started to carry i knew I needed to be as proficient with that tool as possible. This, through practice and training, lead me to "see" my surroundings in a different way.
For me, awareness about my whereabouts and the activities going on around me keeps me safer than someone who is blindly going about their day. This awareness has been sharpened because I have chosen to make sure I have trained myself to use my tools and more importantly how to avoid having to use them too.
That being said, and to be on topic, people scare me more than animals... Especially the people who you come across while in the back country.
