Parents would certainly put a Mr. Yuk sticker on the box and tell their children to stay out of that room. Yet, it is true to life. In every home there is at least one box. It's called a television. There are very few people who think twice before turning it on, and even fewer who decide not to for the sake of their morals.
People readily take on the characteristics of the television they watch.
This is evidenced in many ways. In the 70's, boys dressed like Fonzy and girls like Farrah Fawcet. In the 80's, twenty year old males sported the semi-shaven look of Don Johnson. The root cause of every sin is a lack of sufficient love for God. If we were perfectly in love with our Creator, we would never do anything to hurt Him.
