Well, for one thing, right from the first page -- it requires a school counsellor who a child might have sought out believing that he or she could comfortably and safely divulge information about their growing understanding of their own sexuality ("I'm a boy, but I only like boys," or "I'm a girl, and I like girls as well as boys") -- to then report that information back to the parents. The parents who the child, having, let us presume, some understanding of their parents' stances on such things, chose not to divulge to them.
In other words, take something uttered in confidence in the hope of guidance, and basically OUT the kid. And since I myself have known families that disowned their own children for such things, pretty dangerous, too.
Nice.
