I get your point, and I can see why parents want to be able to decide what kind of education their children receive. But if we look at it from a child's rights perspective, don't sexually mature individuals (those capable of sexual reproduction) have a right to biologically accurate information about how their bodies work, along with information about how to avoid unwanted sexual advances? What about families that don't  protect their children, even those families that are loving and well-meaning but oblivious? Don't "minors" still have rights that should not be set aside by requiring parental consent? Given the fact that sexual ignorance can be life-threatening and place young people in harm's way, I think we need to entertain the notion that children are human beings with rights of their own, not the property of parents to control as they wish.
