The point is that the doctor was bypassing the parent/legal guardian to gain information from a minor--presumably to get that information without any input from the parent/legal guardian.
This is a similar approach that the "education" system is taking in telling the kids not to tell their parents about some form/activity/subject being taught.
It's just another vector on attacking parents' rights. I'd have done the same thing--even if the questions were as innocuous as "What's your favorite color?"
Well, the parent was in the room and saw the questionnaire being passed.
The parent didn’t confront the pediatrician while the doc was still there or after the doc returned.
The bypassing that was done was allowed by the patent.
That’s on her.
