The deficit of knowledge is bilateral. Sure clinicians don't know about patient risk factors, but people get things like rashes very commonly from a wide array of sources. Either way, the parent post was saying that people should inform and advocate for themselves. This is entirely consistent with your message.

I agree with your greater sentiment that people place unreal expectations on their doctors. The point is that doctors are fallible and not omniscient. This is just reality, patients need to be their own advocate.

Blame is beside the point.
