I used to think like you do, so understand that I am happy for you that you have never been in the horrible life threatening situations others have. Enjoy this time while you have it. Your life will never be the same again when it is over.
My change came overnight when a very mentally ill person off medications tried to kill me and my husband. When we narrowly escaped with our lives after racing to the nearest police station, this person hired a contract killer. Local police guarded our house for 24 hours while we packed and told us to stay gone as long as we possibly could, not telling anyone, even our parents and children where we were hiding. We moved every few days for 3 months and spent time in 10 states, terrified every minute. Police insisted we become licensed to carry concealed ( we had never even owned a gun, didn't want one in the house). I can tell you without a doubt that when guns are outlawed, only outlaws will own guns and you will be a sitting duck.
If you are ever in a restaurant, grocery store, or any public venue, and a crazed person starts massacring everyone in sight, it is a carry concealed person who will likely save your life. I have seen it happen: in a grocery store by a disgruntled employee who knifed to death 4 customers before a carry concealed owner stopped him. Just something to think about.
Puhleese keep in mind that trained and responsible carriers do NOT "brandish" their firearms around. I would be the last person in a building you would guess is carrying. But I would gladly save your life without knowing who you are.
