I don't agree that spanking teaches children to fear their mistakes because they cause pain and shame. Don't mistakes still cause us pain and shame as adults? Shouldn't spanking be used to let the child know right from wrong, and prepare kids for life in the real world?
There is no body of research that I am aware of that corroborates your statement that crime has increased as a result of parents condemning spanking as a productive method of discipline. In fact, many states still allow teachers to administer corporal punishment. All solid research available loudly proclaims that we are a nation of spankers and have been for some time. We should show children right from wrong by forming loving, respectful relationships with them, not through fear and control. Discipline comes through teaching and encouraging words, not through rewards and punishments.
