This is not a logical conclusion. Just casue a doctor does not believe in the medication, does not mean that his work "stands" by itself. Pitella is around for less than a few years and much shorter on this forum. WE have no idea how his work will stand the test of time in 8-10 years.
It is much easier for a physician to go along with the patients view, than to actually give them an unfavorable but evidence based opinion.
For e.g. if you have bad diabetes mellitus. Doctor A tells patient i dont believe in medications you can do diet and exercise you will be fine. Doctor B says we need to get this under control for your long term health, unfortunately it will require medications. The basic uneducated patient will probably think Dr A is the better doctor not realizing their bias.
