That upsets me tremendously that people have that type of mentality.
Its as personal and individual a decision as it is for a person to even arm themselves. We might like to think that everyone can be armed and everyone can make decisions about the use of deadly force that fits in with their conscience, but the reality of the issue will not match our fantasies.
The reasons people go out into the world armed vary. I admit, my first duty is to defend my loved ones.
