A man larger than you comes into your house with the intent to assault your loved one what is the correct response?
Me? Stop them by any means necessarily most likely with a gun given that I will be unable to physically stop them otherwise.
I have no desire to kill and dearly hope I will never need to use a gun on anything but when I'm hunting. But I feel safer knowing I could protect myself (or my children when I have them) if the need arose.
