Doctors are supposed to be providing the public with medical advise in line with the standards of their profession, not sharing "opinions" on medical matters whatever the hell that is supposed to mean.
If you can't convince your colleagues that your "opinions" have value and you have such a high opinion of your judgement relative to the rest of your profession that you insist on broadcasting these "opinions" to the world anyway, chances are you have a high level of confidence and a low level of competence and you aren't a very good doctor.
Especially if these "opinions" are outside your specialty.
I know the notion that a doctor should show intellectual humility may offend autodidactics who doesn't even think a layperson should show intellectual humility, but so it goes.
The story of penicillin is an interesting one. As the first antibiotic, it's without doubt single most important medical discovery in modern times. It was discovered by Alexander Fleming in 1928. He left a number of samples of a bacteria to culture while on holiday. One of his petri dishes had been inadvertently exposed and when he returned it had grown a bluish green mold.
But the interesting thing about this mold is that there was no bacteria around the areas where the mold had grown. It seemed to have repelled or killed them. He was quite excited by his discovery. But upon sharing his discovery with his colleagues they were largely dismissive. He gave a number of talks discussing the mold, where people were also universally dismissive. And he even managed to get a paper published, where you can guess the response.
This isn't the end of this story of course, though it is for our purposes. It would take more than a decade but of course eventually penicillin would eventually be refined and shaped into the life saving drug that it would rapidly become. The point I want to make with this is rather evident. Had Fleming taken public views into account before expressing himself it's entirely possible we might still live in a world without antibiotics.
And this story is the rule more than the exception for many of the most important discoveries in the progress of humanity. Human progress is heavily decentralized in no small part because the "right" answer often seems wrong at first, and is rarely enthusiastically adopted when it runs contrary to the views of a day. It was none other than Max Planck that remarked, "science progresses one funeral at a time", precisely because of this.
I don't think the moral of the Alexander Fleming story is the medical community should abolish the FDA and medical malpractice laws so every doctor can do whatever and say whatever any more than the moral of "science progresses one funeral at a time" is we should fire every scientist who is older than thirty.
To attempt to force a populace to discard their own intellect and intuition in favor of simply listening to the 'experts' (who are always self appointed) is the dream of every psychopathic authoritarian who has lived.
