What an awful woman.
It turns my stomach that this kid was doing exactly what I did 20+ years ago to get out of my situation (reach out to the school for counseling and help and affirmation) and the mom is going scorched earth because her right to get her own way "as a parent" trumps, in her mind, the actual health of the kid.
I mean, the kid apparently already has PTSD they were being treated for.
Thing is, kids with PTSD from a young age usually get it from their home life, you know?
And mommy dearest's behavior going nuclear on the school for respecting the student's wishes with name/pronouns pretty loudly suggests why PTSD might have already popped up.
I loathe authoritarian parents. They have the sheer gall to have children, and instead of treating them like people, like real human beings that they have an actual responsibility towards, they treat them like dolls made to prop up their own egos. And if their living doll does something they don't like, no matter how trivial, their response is to try to break it. Awful, awful people.
