One statement people make online (and I've probably been guilty of it myself) is saying very dramatically on a blog comment, "I'm glad you're not my doctor with that attitude!"
I could absolutely understand saying that if the doctor was making fun of their patients in a cruel way or talking about how uncomfortable they are performing surgery. I definitely wouldn't want someone like that as my doctor. No way.
But often what prompts that statement is something entirely unrelated to the practice of medicine. It seems like almost a blanket statement that people use when a physician posts ANYTHING they don't like.
For example, a while back I made a post about how I thought parents who had difficulty finding childcare should have first dibs to get certain holidays off. And several people, in their blind fury, took it upon themselves to comment, "I'm glad you're not my doctor!"
Now regardless of whether you agree with my opinion or not, does that really impact whether or not I'd be a good physician to you? At all? Do you go around polling your physician on all their personal or political opinions, and then make a decision on whether you want to see them or not? Of course, you can't, but even if you could do such a thing, would you?
In my personal opinion, if you would, you don't have much common sense. And that's what I think of you if you make a comment like that.
