These messages are not traumatic. They are authoritarian, and that has become a no-no for some of today's parents. The children of these parents will have a much tougher time than those who do receive appropriate authoritarian messages. Without such parental messages, they will tend to pick up morals anyway, from TV and friends. If my contention is correct that kids often adopt TV values, then TV could well add authoritarian instruction to its kid fare.
Television is a parent for many children today.
Voice these messages in a neither sweet nor gentle tone, but in an authoritarian tone talking directly to the camera. Children thrive on judgments. For adults, judgments create unhappiness. These and other similar messages are taken in by a child and often accepted as truth if said by a parent. Later, of course, the child receiving such early verbal abuse will be a school dropout or in trouble with the law because of violence.
