Just been reading guidance linked to from the D of E website (under campcraft) for dealing with periods on expeditions - all incredibly gender neutral and inclusive, "people with periods" not girls/women, etc, and asking that if the information is copied, the language remain gender neutral, as "not everyone with periods presents as female", etc. Fair enough.

But then they say that pupils might not feel comfortable discussing periods with "someone who identifies as male". Surely that shows that they've not even thought it through, and have just gone through replacing every time they wanted to say 'man' or 'male' with 'identifies as male'. If I were a teenage girl going on an expedition, the last person I'd want to discuss periods with is actually someone who 'identifies as female'. I'd like a woman, regardless of presentation. Or if I really had to, a man, one who wasn't pretending to know what being a female was like. This is one case where they actually need a proper word for someone with the biology that means they have periods, and identification has nothing to do with it.
