Because I am an agnostic
I have no belief that my life will continue beyond what I now have.
Because of this I value my life, and the lives of others, much more highly than I see other people who have faith in a hearafter.
Because of this love of life I want to give myself every opportunity for my life to continue.
I also value the lives of other humans. My Wife, Daughter, Son-in-law, Sisters, Mother, Aunts, Uncles, possible future grand-kids/neices/nephews. I even value your life, sight unseen. Because I think that life is unique, and unable to be reproduced.
If by inaction during a time of crisis I am unable to defend my life or the life of another human than I have failed in my most basic desire.
A gun is simply a tool that can be used for the task of defense of human life. I don't care if it is a .22 or a .50. I don't care if it is new or shiney or old and worn. What I care about is its ability to do what it does and my ability to control it.
