A doctor cannot cure a patient of chicken pox by merely scraping the offending marks from the skin. This superficial solution would be laughed at amongst the medical community. Successful treatment begins with attacking and ultimately eliminating the virus itself. Then, the body will be able to heal itself. The same is true in society.
TV is merely a symptom of violence in life.
Once our value systems, akin to a virus, are reevaluated and altered, only then can society begin to improve. Violence is everywhere. It is an impossibility to avoid it. Refusal to address the issue will not solve it. The parents must stop allowing TV to be the baby-sitter and sole educator of their children.
