I don’t think it’s ethical for broadcasters, newspapers etc to refer to ‘trans children’ at all.
A poster in a now deleted thread talked about 'trans children', so I asked them to explain what they meant. They said a child who 'needs to transition'. I asked for a more detailed explanation of what they meant, but I didn't get an answer before the thread was deleted, but they asked me what I thought a 'trans child' was. I said I didn't know, because I don't think it's possible for a child to be 'trans'.
To expand on that, I think a 'trans child' is a child who has been persuaded by the trans cult to think that there is something wrong with their body. Or that the way they want to live is incompatible with their sex, so they need to change their body to resemble the opposite sex in order to live as they want to.
I still haven't seen a definition of what it means for a child to be 'trans' which indicates that my definition is wrong. These children are caught up in a dangerous ideology which is being supported by media outlets like the Guardian which are behaving in a totally irresponsible manner.
