(1) Networks should not present children's shows that contain violence. (2) Children fed a constant diet of TV violence begin to believe that brutality is acceptable.

(4) Another reason for keeping violence out of children's shows is that young viewers may get the idea that violence is not really painful. (5) For example, my neighbor has told me that after a Saturday morning of violent cartoons, her son Paul tends to hit and bully his sister and then seems amazed when, unlike the smiling cartoon characters, she cries. (6) Most important, the consequences of letting our children watch these shows are frightening to imagine. (7) We may be raising a generation of adolescents and then adults so used to watching cruelty on television that they will not be moved to stop it when they see it in real life.
