The people of the United States have been fighting for and against spanking for about 40 years. At has been at a loss with the current laws forbidding spanking.
One doctors argument is that spanking teaches children to hit, because of being hit. This is not true. Because the child doesn't like being struck after being struck, they will not do it to another person. They learn why it is bad, from being spanked.
Another argument is this, "This increase in aggressive behavior is thought to reflect the child's perception that hitting is the way to deal with anger and frustration." The idea behind that quote is that a child's mind is as premative as an animal.
Doctors used abuse cases where parents had beaten children black and blue, even to the point of death. While these bad things have happen, it is a small percentage of the population. Just as car crashes are a small percentage of drivers, these abuse cases are small percentage of spanking parents. We should not stop driving automobiles because people disobey the road rules and crash them.
The facts are in, the violence in America has more than doubled after with the no spanked generation of children. The murder rate is much, much higher than in generations who where spanked.
Proverbs 22:15 "Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him."
Proverbs 23:13 "Withhold not correction from the child: for if thou beatest him with the rod, he shall not die."
Proverbs 29:15 "The rod and reproof give wisdom: but a child left to himself bringeth his mother to shame."
