Responsibility to family and community

Again, a little bit from Jeffrey Snyder and A Nation of Cowards, in defense of the morality of self-defense:

One who values his life and takes seriously his responsibilities to his family and community will possess and cultivate the means of fighting back, and will retaliate when threatened with death or grievous injury to himself or a loved one. He will never be content to rely solely on others for his safety, or to think he has done all that is possible by being aware of his surroundings and taking measures of avoidance. Let's not mince words: He will be armed, will be trained in the use of his weapon, and will defend himself when faced with lethal violence.
