I can't abide a man that wouldn't stand ready to kill to protect the innocent.
Ditto... that would extend to women as well.
I would not be comfortable with my sister being married to someone not willing to shoot, stab, batter, beat, tackle and die for my sister and their children.
My wife's differing outlook on shooting to stop didn't bother me much until we had our first child... maybe even out second child. She made the comment on more that one occasion that she didn't know if she could shoot someone that had broken into the house. I put it in very unpleasant terms whey she should shoot said someone. I asked her how she would feel if, through some unlikely twist of fate, someone broke in the house, encountered her with the gun went up stairs and raped and butchered our 6 year old and 2 year old. I painted it in a very very ugly manner.
Now the bad guy would have a couple rounds of 12 gaugs in him before he touched the first step.
Call me whatever you want to call me but if I were home alone and someone happened into the house and made a threatening move or declaration, I'm not entirely sure what I would do. On a conscience level, I don't fully think that I would be comfortable witih taking a life if mine was only casually threatened... From someone not visibly armed 7 yards away. But that darn muscle memory may kick in and he'd get a double tap COM before I had a chance to really think about it. I'm not sure I'd have a problem with either response.
On the other hand, I stay up pretty late most nights and if the wrong guy walked through the door with the wife and kids up stairs, I really don't think he'd have a chance to turn around. Where we live, it isn't likely he was drunk and wandered into the wrong house. And if lights didn't come up the driveway and he didn't knock or ring the bell, he's up to no good. If he was 14 or 15, it would probably be different, but if you live to be 30 years old and don't realize to knock on a stranger's doorbell, then this one just might be the last one you walk through.
