Agree.
Working in education I can see why there needs to be some sort of policy. It was getting to a point half a class would be expecting different pronouns and names all the time and used as it a control way. And I believe that really minimises the experiences of kids who are genuinely struggling.
But to shut down the conversation at all is counter productive too. And ime some pupils questioning their identity aren't actually trans but have other issues going on,are seeking attention and/ or control and need the adults in their life (and sometimes the ones who listen are at school) to support them.
It's not an area that a black and white policy can be drawn up.
