Male child comes into school and announces that they now identify as a girl/cat/clown/cheese grater, etc. Peers and teachers too scared of repercussions to question this behaviour, so individually and collectively affirm child's new identity. Parents do likewise.

Eventually it transpires that this change of identity was precipitated by psychosis, was a symptom of a serious mental disorder, and that, owing to uniformly unquestioning affirmation, the window for early intervention has been missed. ("Getting help quickly is really important if you're experiencing psychosis," according to the NHS.) Treatment is therefore far more lengthy, difficult and traumatic (and expensive for the NHS) and many disruptive years of psychiatry and periods as an in-patient in psychiatric wards follow.
