Back in the dark ages, my 9th grade biology teacher had to teach reproduction. He was very clear before he ever started. Said I can tell you the anatomy and the physiology, what parts are and how they work. You need to talk to your parents about everything else. He drew the line very clearly and diverted questions (even from the “tough kids”) that moved into morality.
I still respect him for that. After all it was a public school in the 70’s.
A wise teacher whom I can totally respect.
I have yet to see a coherent argument against this crucial role of parents; other than the circularly reasoned (and self-serving) argument that "many" parents fail to address the topic.
If that view of parents' role in society makes any sense, might as well have the nanny state start feeding our kids, clothing them, sheltering them and providing needed health care... ... wait.
...never mind...
