What do you do? Someone spends over 30 years treating patients for a particularly difficult to deal with disease and after many successful results and praise from patients writes a book on the subject explaining the reasons for their success. If not cured of the disease altogether, the reduction of the adverse effects improves quality of life so the patients can function in society once again.
Then, a nurse who has a particular interest in the disease who disagrees with what she reads in the synopsis of the book writes a damning comment about the doctor's methods. Her comment indicates she didn't read the book. However she rated it with 1 star.
Subsequently, other sufferers of the disease who claim they were mistreated by the medical profession decided to add their opinion with "Well done" comments.
It seems that from the comments no one has actually read the book. The Doctor's reply to the nurse's original comment correcting a misconception ended by asking that only people who have actually read the book comment.
That was ignored.
