Obviously what we let our children be exposed to will differ a lot based on the child's age and maturity. However, what standards does your family have as far as sex, violence, and profanity go in media?
Books, movies/television, and video games would be the biggest areas.
As my children are still young, we try to shield them from profanity and anything more sexual than kissing (think Disney Princess level). Mild cartoon type violence isn't really a problem, but I know that even if they were to walk in on a movie that my wife and I were watching, we would be more concerned about sex or nudity, and profanity, rather than violence (not gorey or scary though).
I know when I was a boy (probably 12 or 13) my parents bought me a computer game that was rated M for violence. I was surprised and remarked on it. My dad pointed that I had no problems differentiating between reality and fantasy. At the same time, we had the TVG box that would mute swear words in movies and TV shows. We couldn't watch Friends because the characters had premarital sex. (However, they did give permission to watch the uncut version of Schindler's List in 4th grade.)
I saw an explanation somewhere that talked about this seeming inconsistency... Violence in movies is pretend, profanity is part of a character, but when actress is naked onscreen, that is actually somebodies daughter being exposed up there.
Thoughts?
