Sex, violence and death, is the school ready to talk about them?

It is not a secret that these three topics I chose from the eternal list I could write, are three of the toughest topics to deal with children, and it is evident that  when it is needed to discuss them, nobody dares to take the responsibility. There are many people who defend the idea that school should not be in charge of these duties because they are not part of the main function of school and beyond, it is the family who should attend these problems and get to form children from home. Nevertheless, is not the school whashing its hands of this trouble? Does this position hide an Education Department's apathy and incompetence attending these matters, and as a result of that lack of policies directed to manage this situation and teachers wrong prepared for dealing with challenges such as them? How could school treat this situation? and are actually the families the unique responsibles of this part of children's formation? Who must explain a child what an homosexual relationship or what pregnancy implicates? Who must guide a child when he faces a close death?  The discussion is open.
