I was talking to a friend last night who is a (lovely, kind, well meaning) teacher, she was worried about a female pupil who is identifying as a boy, along with several others. She thought this pupil would be very upset at the judgement.
I think the ethos in schools on this is part of the problem . If you are completely affirmed in this mid-teen dysphoria by everyone at school, if your teachers , who you trust, now call you a boy , where is there to go when you grow up a bit and start to regret that identity? Not surprising at all that girls tend to suddenly want to be boys as puberty starts, or half way through. Being a teenage girl is really hard, even more difficult now with porn everywhere.
There are an awful lot of careers it seems propped up by this, from Stonewall to Mermaids to various medical staff. It isn’t in the interests of any of these people for there to be no trans children.
