I think it would be very helpful in this situation if
@Jonathan Edwards, with input from members, wrote an article setting out the evidence for and against the usefulness and validity of MCAS and hEDS as diagnostic labels, his views and his concerns, particularly in the context of these being added to ME/CFS diagnoses.
It would need to also include a clear statement that the symptoms are real and have biological causes, often unclear, and the problem is with doctors either misusing or disbelieving diagnoses and the lack of clinical trials for treatments.
If we had a single clear statement people could be referred to, we would not need to keep having this same conversation, and we would have something to refer people beyond the forum who may be misquoting or misunderstanding the views being expressed.
