Can't be stressed enough that the oversight of a child health issue by some of the most unsuitable people in the world to have an influence, is literally a disaster for vulnerable children.
This.
Not to mention the political idea of no qualifications in the field being needed other than having the characteristic in question leading to people for example such as A. Challoner, advising on matters directly affecting safeguarding policy while holding no qualifications or training in safeguarding and an inquiry after repeated discussions with Challoner having to record that Challoner was not capable of understanding safeguarding.
This is a political point that is going to have to be unpicked: when it comes to safeguarding, when it comes to national policy, when it comes to diagnosis, and advice and regulations that affect other bodies for example Equality Law where there are 9 separate groups to consider, being qualified in the field and having the training and experience to give this advice has to be a thing. You may take policy advice from a group solely based on what is popularly called lived experience, but the harm has come from not ensuring proper balance and impartiality in taking this lived experience advice and being drawn into political prejudice and bias between the groups, and also from buying into a political idea that experts and qualified professionals know nothing, compared to someone who has identified as living with a characteristic in question.
A lot of this has been tried now, in a rather irresponsible free for all experiment while a lot of professionals who should have done a much better job have been asleep at the wheel and failed in safeguarding on multiple fronts. It has been proven to not work, and to cause a lot of unintended harms and consequences. Letting it continue to roll is no longer an option.
