Domestic Violence: When Should A Couple's Violent Private Fight Be Made Public?

The debate over NFL's suspension of Ray Rice after the video of his physical altercation with his then fiance, now wife, Janay Rice has prompted many public figures to address the issue of domestic violence. When should a couple's private conflict become an issue for public scrutiny? If a couple has a violent fight and chooses to forgive each other, should either one be fired from a job? What should boys be taught as children to prevent violence toward women as adults? What about women who hit men, expecting the men to take it and not hit back? Can we agree on a code of conduct in which no one inflicts physical violence on any one for any reason other than defense of ones life? What about whipping a child? Should parents be judged as abusive if an act of physical punishment leaves marks? Or should parents learn a better way to guide and teach children without the use of physical punishment? How can we evolve into a non-violent society?
