Why are we blind to 99% of Child Abuse?

Child Abuse in on my mind right now. I have written a screenplay for a feature film that I'm already in early talks to produce. The bad guy in the movie is a child-rapist / child-killer. His presence alone justifies the anger of the heroes and creates the tension in the film. Yet I don't think I can make a movie that is a shlocky exploitation film. The subject matter is a bit too strong for something that careless.
