I would absolutely differentiate between verbal attacks and physical violence. If I let myself be provoked into physical violence, the problem lies within me, I'm the one who will and should end up on the worse end of that legally (and morally because physical violence as a mean of resolve of conflict outside of sports competition is a clear sign of mental weakness). Being offended, being insulted and anything of that kind does not justify physical violence, even if I try to justify it as a "natural" reaction as much as I want. It takes and active, deliberate action for me to swing my fists in someone's face. Fights belong in sports, not into everyday interactions of a civilized society, not even the most heated, intense and personal ones. These legal troubles I or you would get exist for a good reason. I'm on your side concering accountability for ones words, physical violence isn't the right repercussion though.
