There is a harm - an unidentified harm. Precocious puberty is a harm.
Precocious puberty is increasing across most of the world. It is happening too fast to be explained by human evolution. Therefore there are triggers. Those triggers are being investigated but no single factor exactly correlates, suggesting that two or more factors are present.
In South Korea, menarche occurred at average age 16 just forty years ago, now it is twelve. Breast development likewise is precocious by a few years. Higher BMI correlates somewhat, so do some environmental pollutants such as BPA. Other factors that do somewhat are family stress levels, and changes to the night sky.
Concern about the use of puberty blockers at age eight is legitimate concern. However the pool of children involved as trans children is at a micro level, the pool of children involved at the macro level is huge.
A puberty blocker trial may be helpful at the micro level, but we need the application of some more serious science at the macro level.
To anticipate the questions that try to push responsibility onto me - no, I don't think there is evidence that puberty blockers are safe to give to eight year olds and to continue their use for ten years - and no I don't believe that eight year olds have capacity alone for bodily autonomy.
I don't believe that any health secretary or court in the land has the competence to make these decision. I think that only a multi-disciplinary team including parents can exercise best judgment to decide treatments. I think there needs to be a small amount of wiggle room to allow treatments to be prescribed in good faith without recourse to liability claims. I think that something like two years should be close to optimal in terms of a pause. I don't think a switch to CSEs should be the default. I think this is something that needs very careful management, that given the state already says that ''the welfare of the child shall be paramount'' that the resources must follow each case without exception - if not it is the state itself that is liable.
I think presumption of ''probably just gay'' are just lazy ill-informed opinions that should go straight to the bin.
