By watching violence on TV, playing video games that glorify violence, and by identifying with violent heroes. By refusing to understand the connections between previously experienced violence and the violence actively repeated today. The ignorance of society is thereby perpetuated. Because of obedience to violence as a child, by readiness to obey any authority which recalls the authority of the parents, as the Germans obeyed Hitler, the Russians Stalin, the Serbs Milosevic. Conversely, some become aware of the repression and universal denial of childhood pain, realizing how violence is transmitted from parents to children, and stop hitting children regardless of age.
People often ask for alternatives to spanking.
There is no alternative to hitting children. And this is the only thing you achieve with spanking - but only for a while. Later the whole family will have to pay the price for their obedience. And this you should know just from the first day of your child. Then it is up to you to make the choice consciously.
