Conversation has moved on but need to come back to this point;
"gender questioning" is not a protected characteristic.
This should (ideally) take a "gender questioning" child back to diagnosis and only those who've been given a diagnosis get a potential title of "trans child" and so the protected characteristic, in the most extreme circumstances and with huge amounts of professional involvement.
The term "trans child" as a common term needs to both be challenged and be phased out.
That's the label, the diagnosis and affirmation. Not self diagnosis.
Schools, teachers and the media need to be extremely clear who they're talking about here.
It's really significant that the term is "gender questioning" and not "trans children." It also means charities have to change their language.
Again, Deprogramming is going to take a while.
