There was nothing wrong with the advice in this article. Nothing. I am kind of glad they did it. It's not a book on sexual abuse and a comprehensive guide to all of the various ways a child can be victimized. Nor is it an exhaustive list of anyone who can abuse a child.
I think its absurd to find fault with it just because it doesn't list every tactic a molester can use or list every person who could be a molester.
