And there should be programs for these youths to help them out.
You want government employees determining whats okay for the kids, but have parents take any repercussions. Either parents are responsible for their kids decisions, or teachers, can’t have your cake and eat it too.
Exactly how are these kids meant to find out about these programs to help them if there's literally nobody they know that they're allowed to disclose this information to without their parents immediately finding out about it?
You say "government employee" like as though it's a tax collector you're putting in charge of these kids.
At least in the UK, teachers have to undergo a lot of safe-guarding training before they're even allowed to teach. They're supposed to protect your child's safety, even from you if required. That's serving the tax-payer, and this law jeopardises their ability to do so in that scenario.
Therapists have an obligation for confidentiality, teachers are public servants, they should serve the tax payers.
Yes, because children (without the aid of parents) can afford a therapist. That's your worst take so far.
Also, you missed the second part there where you can bypass all of this by simply fostering an environment where your child feels safe to tell you this in the first place. If your child isn't telling you something that fundemental about themselves, it's because they don't feel safe to do so.
