I didn't take it to mean something that they didn't know answer. But as relative experts in the medical field, they considered it a good and valuable question.

I was contrasting this with keyboard experts who berated me for asking but know even less. The former are pro-science. They have studied. They didn't know. They valud the question.

Others knew less and didn't even see why it was a valid thing to wonder about. Instead of any scientific answer, they regurgitated garbage.
