I did read the whole thing, and I gotta tell you, I found it extremely interesting. It's another way of telling people that they shouldn't be looking to musicians, althetes or movie stars to be role models for their kids. Be one yourself. Live what you teach, practice what you preach. I grew up in a broken home (parents divorced when I was young) and I, too, could identify with a lot of the lyrics being sung by these artists...they were talking about my life as it was then. Unlike those artists, though, I used my experiences to learn what NOT to do as a parent instead of using it as a cop-out for bad behavior.
Therein lies the difference between you and Eminem.
