Again, if the school would out the kid and the kid doesn’t want to be outed, that’s not going to result in the parents finding out - it’s just going to mean the kid has to hide their identity at school so the school doesn’t out them.

So there’s little possibility that this would enable parents to help their kid - absent the kid making a mistake, they’re not going to find out either way, you’re just taking away the one other potential safe space the kid had.
