There’s a gap between questioning and transitioning
If Jimmy is now going by Cindy, that’s a social cue of transitioning.
Kids need people they feel safe talking to. Kids need to be able to ask questions about the world without feeling like they’ll be punished. You mentioned in other comments about programs to reduce abuse, but what about something as simple as:
I agree they need people they feel safe talking to. Schools have counselors.
It shouldn’t be up to teachers to determine the morality of what the kids saying and whether they should share it with the parents or not.
Well, little Timmy, you shouldn’t have told me that because I now need to legally tell your parents. Hope you’re ready to feel unloved just for asking a question, nerd.
See? You have to be incredibly hyperbolic to even create a situation where it’d be bad for parents to discuss with parents about the children’s behavior.
If instead of a teacher, your kid starts going to church and has these secret meetings with pastors and priests, are you comfortable with that?
