Did you actually read what I wrote? I didn't say anything about the state. Parents send their kids to school trusting that the school will take care of their kids while they are away. Parents trust that the school will notify them if things are not going well or if there are issues/behaviors that the parents might want to know about.
If a kid was trans and the school knew about it and did not tell the parents, or possibly even advised the kid about being trans. What happens if that kid shoots someone else or commits suicide? I would sue the school district for failing to act appropriately.
Maybe there are other things that are causing the kid to make the claims such as sever underlying mental health issues. The teachers and school do no know the full scope of what is going on with that child. It is the schools responsibility to notify the parents of changes with the students. Anything less than this will lead to lawsuits against the school.
Here is a story from just last year where the school is now being sued for failing to take appropriate action. Why would any school want to take on this responsibility.
The reason this is so important specifically for trans kids is because of the crazy high suicide risk for trans kids. I would also hope the school would notify the parents if they saw a distinct change in the behavior of the child indicating they may be severely depressed or have a mental illness.
The lawsuit says "multiple concerned parents" alerted school officials to violent threats two weeks before the shooting at the Michigan high school, only to be told there was no reason to worry.
