No. 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.
When I carry a firearm, you cannot deal with me by force. You have to use reason and try to persuade me, because I have a way to negate your threat or employment of force.
The firearm is the only personal weapon that puts a 100-pound woman on equal footing with a 220-pound mugger, a 75-year old retiree on equal footing with a 19-year old gang banger, and a single guy on equal footing with a carload of drunk guys with baseball bats. The gun removes the disparity in physical strength, size, or numbers between a potential attacker and a defender.
A mugger, even an armed one, can only make a successful living in a society where the state has granted him a force monopoly.
Then there's the argument that the gun makes confrontations lethal that otherwise would only result in injury. This argument is fallacious in several ways. Without guns involved, confrontations are won by the physically superior party inflicting overwhelming injury on the loser.
The gun is the only weapon that's as lethal in the hands of an 85 year old lady as it is in the hands of a weight lifter. It simply wouldn't work as well as a force equalizer if it wasn't both lethal and easily employable.
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.
