Recently ended up talking to a few 11-13-year-olds about why a girl may dress up as & pretend to be a boy, now & historically (eg. to increase freedom of movement in Afghanistan; to be safer on the streets when homeless; to access an otherwise inaccessible location/resource in different times & places...) The language they used was fascinating, & disturbing to me. Our focus was wholly unrelated to transgenderism, yet one repeatedly referred to her "changing into a boy" / "becoming a boy", & another to "changing her gender".
It's easy to assume this was just clumsy expression from young-ish children, but, if so, surely "dressing up as" & "pretending to be" are just as accessible? And, certainly, they'd feel more accurate, logical & natural to me, given the context.
I do feel this fairly clearly shows how this movement is changing our language. Which would be fine IF these changes weren't so politically-driven & problematic. As it is, these kids are using words that, whether they consciously recognise (& believe!) this or not, DO reinforce the message that it's not natural to a girl/female to wear boys' clothes or behave in ways a society may regard as "boyish". In order to adopt this image, these behaviours, she must "change" into / "become" something else.
It's something so very slight, so easy to dismiss as insignificant, but it really concerned me. Language matters, this kind of distinctive phrasing is clearly coming direct from rainbow-progress lessons & marketing, &, ironically, it very clearly implies that gender IS "binary", that you ARE either one or the other. How can people like Emma D'Arcy not realise that they're moving us away from 'girls & boys can behave however the heck they want' into reinforcing the rigid binary she believes they believe they're breaking down?!?
