Wow, I love it when people make an accusation and it's better leveled at them. It's your tone that I don't like.
The original posted was expressing a well-formed opinion, one that is backed up by a lifetime of experience, his and mine.
I can't claim to have an exotic or serious disease, but I do have a lot of chronic medical issues. I cannot tell you how many years I've wasted dealing with Dr's that 1) thought they knew what they were doing (YES, behaving God like!), and 2) had no clue.
The problem with Dr's is they are taught to project confidence, at the expense of their patients.
