unsubstantiated self-harm claims

I work in a Victorian high school in a wellbeing capacity (and am a registered health professional).

I have been given the schools guide from https://transcendaus.org from a Secondary School Nurse (DET employee) as what we should use to support trans students.

In it it mentions in one of the side bubbles on page 6 that using the wrong pronouns, deadnaming, dividing the class ‘by gender’ or forcing a ‘non binary’ child to use a toilet of either sex can cause the student to self harm.

This certainly goes against ethical reporting on self harm.

Clearly, I’m not in favour of this gender ideology but I certainly can’t be out about that at work.
