I have no problem with some one protecting their life, safety or personal property. (even their family members) Do the cops protect you? NO. Their job is to try to figure out who did it to you, not to stop it from happening. After all it is not a crime until after the action is done. I stand behind anyone who stands up to the bad guys and protects themselves.
I carry a gun with me most of the time, outside of work. I have never had to use it. My kids don't even know I have it, as I have not even had to show someone I was carrying. I hope that I never have to use it, but I am not afraid of using it when the need arises.
If the bad guys knew that more of us good guys were carrying guns, they would be less likely to commit the crimes and risk their life's.
