"Human beings only have two ways to deal with one another: reason and force. If you want me to do something for you, you have a choice of either convincing me via argument, or force me to do your bidding under threat of force. Every human interaction falls into one of those two categories, without exception:

Reason or force, that's it.

In a truly moral and civilized society, people exclusively interact through persuasion. Force has no place as a valid method of social interaction, and the only thing that removes force from the menu is the personal firearm, as paradoxical as it may sound to some.

...

When I carry a gun, I don't do so because I am looking for a fight, but because I'm looking to be left alone. The gun at my side means that I cannot be forced, only persuaded. I don't carry it because I'm afraid, but because it enables me to be unafraid. It doesn't limit the actions of those who would interact with me through reason, only the actions of those who would do so by force. It removes force from the equation...and that's why carrying a gun is a civilized act.
