So you wish to mandate “civility?”
Free will, and the liberties we are still allowed to enjoy, present us with opportunities to freely exhibit civility.
In Muslim-dominated cultures, women and children have “protection”, supposedly of their families. Doesn't seem to help much. “Honor” killings happen frequently and at the hands of other family members. Nevertheless, civility and kindness towards others does exist in those cultures; it is just very hard to find during periods of civil unrest and war.
Here in the U.S., we have laws about rape and murder in a justice system based on equality before the law. Those laws do not say that only the morally pure shall be treated as victims. It doesn't matter if the victims are a homeless man and alcoholic, a runaway child trying to live on the streets, or a prostitute attempting to earn a few bucks. As imperfect as the system may be, equal rights is better than no system at all!
Statutorily required civility would be unenforceable. That shouldn't prevent families from trying to rear their children to be moral individuals who respect others.
