fear
Amen.
I hope you don't mind my chiming in on one piece of it:
"Answer: "They" are scared of you...."
IMO, behind their fear of "you" there is just plain Fear.
Everyone projects, and of course health care "experts" are drinking their own brew. Unconsciously they feel every bit as vulnerable as they want their patients to feel--they have to; it's part of the healthcare model they've bought into; it's in the brew. They "know" they *themselves* can be set upon at any second by disease and death, and when that happens they'll be the bewildered, weak, dependent, terrified, enervated creatures they see from the other side of the exam room every day.
They handle these fears by projecting their vulnerability onto others and then assuming the role of Authority with the Answers. It's essentially a splitting of the Self that gives temporary relief from the fear. As long as they are safely ensconced in the role of Authority they do not feel the fear, they feel invulnerable and powerful and safe. Heady stuff.
If someone challenges that Authority it threatens the bargain they've made; it threatens their sense of invulnerability -- so they resist it.
They are victims of their own propaganda. It's too bad, really, considering the fact that some of the best minds in the West go into medicine. What a f^cking waste . . .
