So let's say a parent WILL NOT talk about sex with their kid. For whatever reasons. Should the school be able to say since you are refusing to do it we will decide on our own how much your child should know about it. That is why I say stick with the science part of it. The child already knows what needs to be known. Whatever flavor the parent wants to add to take it the extra mile should be their decision. Sex education covers a lot. What if your child is confused about their sexual orientation would you prefer the school to be the one to discuss that with the child? Even if a parent is refusing to discuss it the school should still not make it their business. That in my opinion is just plain oversabi. Nobody taught me about sex even though I was very curious about it long before I was bold enough to do it. It was the facts I knew about it that played a big role in me not jumping in too early. Even when a family member went a little further to educate me she still could have been reading out of a science book. I got the gist of the matter.
