The objective and little disputed consensus among social scientists who study the effects of violence and sexual exploitation in the media is that it contributes to the problem of crime, including physical abuse and sexual assault. Keeping children from viewing gratuitous sex and violence does not protect them from it. That this material exists and is viewed by many makes the world more dangerous for children. The belief that the home is refuge from the world is a myth. The home is often a dangerous place for children.
Child abuse is the leading cause of trauma deaths for children under eight.
Industry-sponsored rating systems assume that parents protect children. In many cases, this assumption is tragically wrong. Children and what they view are not the problems. It is the vulgar and sadistic images adults call entertainment that is the problem. Adults set examples for children.
