Diamond lawDawg; I totally agree when it does go to a life threatening level you fight, and fight to win period. One thing I have noticed through the years, some people ( most not ) act 6 inch's taller and 50 lbs heavier when they are armed. They take chances going places and say things in places they normally wouldn't.
It astounds me even in this day the amount of people who leave house doors unlocked, even all night, and car doors unlocked while driving around. We cannot defend against everything, but a little common sense can be a big payoff. Sadly I have known quite a few who have a total lack of common sense, I have to think either your born with it or your not and for many people they can't be taught to think independently. They can be trained but if they haven't the ability to adapt on the fly on their own.
The real danger to America is not abroad but within..
Having an open mind is a good thing, but not so open that your brains fall out!
Save America, abort liberalism.
