"an armed society is a polite one"That comes from science fiction writer Robert Heinlein's book Beyond This Horizon. One sub-theme of the book is the carrying and use of firearms. In the novel being armed is part of being a man; otherwise he wears a brassard and is considered weak and inferior. Women are allowed but not expected to be armed. Duels, either deadly or survivable, may easily occur when someone feels that they have been wronged or insulted, a custom that keeps order and politeness.
Is a work of science fiction one we should be modeling society upon?
