Yes, OP, but how would you feel if a news story got out about a girl who had told her parents that she was pregnant and wanted a termination and she had been thrown out in the street or Heaven forfend, killed?
The laws and the regulations are there to strike a balance between the rights and the protection of the individual and the rights of the parents.
I really doubt that the school and the medics between them told this girl that it was perfectly OK for her parents not to know and then just waved the termination through.
Ultimately the decision that this girl was competent to choose a termination was made by doctors, not by teachers. I find it very difficult to see any argument for the girl's teachers to have told the girl's parents when the doctors clearly were not going to - it would have been a horrible betrayal of trust and would have left this girl without any trusted authority figured to turn to.
Of course it would be better if the parents had been involved, and who knows perhaps this girl will one day feel able to talk to her parents about this - but on the day she was not, and the laws and regulations were invoked to provide her with an outcome she was legally entitled to. It's sad that this happened, but it is not wrong.
You are pro-life, aren't you? Quoting America as an example of how the rules should be on this is a bit of a giveaway.
