“What are the different gender identities?” asks a little boy in one of the nine new BBC Teach films put out to support the personal, social and health education (PSHE) curriculum in schools – to which his head teacher replies: “That’s a really, really exciting question…”

Actually, it’s not. And the answer is still less exciting.

Which is perhaps why rather than give the boy a bald, biological and distinctly boring fact – “two” – the video cuts to a Relationships and Sex Education teacher, hopped-up on her own gaping-mindedness: “You know, there are so many gender identities,” she enthuses. “We know that we have got male and female, but there are over 100, if not more, gender identities now.”

Even by today’s Emperor’s New Clothes gender diversity narrative, 100 is pushing it. ‘Woke’ Facebook currently lists 71 complex and hilariously repetitive options for those who feel manacled by the oh-so-reductive ‘male’ and ‘female’.

And, despite four years at medical school (where you’d hope the basics had been covered), your local GP will ‘only’ recognise six genders: male, female, gender-neutral, non-binary, gender-fluid and gender-queer.
