Look to Hollywood! It is hard to find a popular program that doesn't portray sex with anyone and everyone for fun. If we think the violent video games lead to violent behavior, what do you think programs promoting indiscriminate sex promote, yet they are applauded by adults as funny and so to children, good. There used to be standards on TV, Lucy and Desi even had separate beds!
As a teacher I used videos and films to teach my subject, so what do you think TV teaches children now??
