I already posted my surface reasoning for going armed , like the rest of you it is for protection from the dangers that life presents.
But the question has still been kicking around in the back of my mind. I have carried for nearly 30 years and only had to draw once, where as I have used spare tires, and fire extinguishers several times in the same period and the knife I carry and use just about every day could have protected me just as well in the previously mentioned incident.
It seems to me that there is a sub conscious cultural influence involved.
Before any one starts freaking out let me be clear that I'm not using that term like the ignorant and liberals who would eliminate our right. I am referring not to "Americas culture of guns" but instead to thousands of years of influence on the human mind.
For thousands of years there has been a fundamental difference between those who could use arms and those who could not.
Look at relations between men and women, the man, larger and stronger, was better equipped to club things that threatened the cave, or could be eaten, became the dominant member of the pair forming a pecking order that survived until the 20th century. Tradition shows that those who bear arms are some how "better" than those who do not. It seems trite to say but the bearing of arms separates the freeman, Master of his own destiny, from the subject and slave who must serve a master and rely on the Masters protection. Even in "peaceful" situations the carrying of weapons is an emblem of both rank and responsibility, Military Officers and NCO's, even Ambassadors from many countries, (America included ) still wear swords at formal occasions, on one hand it symbolizes the power vested in them to practice violence on behalf of their nation, on the other hand it is a symbol that they are trusted to use that power with restraint and for the good of their society.
Beyond the banal answer of "self defense" it seems we carry guns as an emblem that we are FREE people and each in his or her own way is willing to put themselves between the forces of civilization and the Barbarians who would tear it down.
