I only tried talking back to my father once. He was across the room so fast that I thought I was struck by lightening. And I thank God that while I was at home that policy was maintained. Zero tolerance is an unpopular policy today. That's why our society is in the mess that it's in.
Groups of people show open contempt for judgments handed down by our judicial system.
The government then shows contempt for it's own laws by negotiating with the rebels and then praising them for their rebellion. Unfortunately many parents make the near fatal mistake of believing that their child is not born with the spirit of rebellion. The Bible says that every child is born with a rebellious spirit and God expects every parent to break that rebellion in their children. That's what the fifth commandment is all about. Rather than deal with the rebellion, parents choose to negotiate with an immature mind.
