It's also a question that doesn't ask about the law, but it sounds close enough that it makes sense in the same sentence. Would I want to know if my kid decided to change their pronouns or name? Absolutely. Do I think their teacher should be legally required to tell me about it, let alone ask me for permission first? Absolutely not. I would hope my kid would want to tell me themself, and if not that's my issue to deal with and not the government's.

As you said, it's absolutely a loaded question, and with that wording I'm honestly surprised it's not higher than 78%. What kind of parent wouldn't want to know what's going on in their child's life?

Edit: I am ashamed to admit I based my facts off the previous comment, and after reading through the link the questions seemed like they may have been slightly more clear. That being said, I support knowing, I do not support this law or any other requirement for the teacher to inform me or ask my permission.
