Calling worried patients with scary symptoms "nuts" and their issues "crap" really sums up the sort of thing I am talking about and is what makes patients afraid their provider isn't going to do their best to help them. Empathy is required for good healthcare. I recently got another confirmed and terribly depressing diagnosis of an incurable issue, but the provider I was working with was so kind, caring, and informative it reduced the mental impact as much as is possible. A dismissive provider, who was ultimately wrong, a few weeks before had me in an even worse head space than normal until I got to someone good. When I reached out to the wrong one to notify them they didn't seem care at all and dug in harder despite the proof/labs etc.
"A few bad apples" isn't because of the few bad apples. It's because the farmer decides all the apples are rotten, and throws them all out with the few rotten ones, while telling others constantly about those rotten ones as if they are the norm.
