Irony? Hypocrisy?

What's a Christian doing with a Concealed Weapons Permit and talking about self-defense?

I am confronted by an attacker. It will be he or I, and I have the means and the opportunity to make it him. God has blessed me with the knowledge of himself through Jesus Christ. It certainly does not appear that He has yet blessed my attacker in such a way. Shall I let him take my life as part of my Christian witness?

What if the attacker is confronting my wife or my child? Is the answer different?
