"Virtuous Violence"

A lot of the references referred to "virtuous violence" as a term used by parents to justify spanking and even forms of child abuse. It also has had religious connotations in some references.

Along with representations of hell, it is the destruction by arms of large human groups which nourishes most assiduously the popular imagery. If violence ceases to be demanded by right and justice, will we have to deal directly with the monster who inhabits each one of us? . . . The purely political categories disappear and any position, opinion or policy is classified as good or evil. . . Violence has never tried to look so righteous.”
