I want to add my 100% backing of parents being able to decide what to allow their children to have knowledge of. When sexual content is taught in the school, there are children from all different levels and backgrounds. It is not appropriate to assume that there is one curriculum to cover all students.  Please, do not allow for a class to uncover unnecessary information for a child that should not have to worry with it. Teach our kids English,  math, social studies and science basics, ie. plants, solar system, cells, but not life science.
