So my hypothesis is that groups of experts, or expert-adjacent, that are used to dealing with the public pelting them with questions and then ignoring them anyways, will be prone to shooting down smart, good faith questions too.
Here's an analogy most people here should respond to: a family member asks, "you know about computers, why isn't my [insert some app or website] working?"
Now, most of the time, do you think that they actually want the details? Even if many possible explanations leap to mind automatically, maybe it's some weird application that you've never heard of, and you really don't want to take the time at that moment to go figure it out for them. But generally, they're not asking for you to layer on the jargon and actually explain the nitty gritty details of why something isn't working, they just want you to make it work. Very seldom, sometimes that person really wants to absorb some real knowledge and learn. But that's not the common case by far.
So if most of us here are "computer people" to the lay public, then people working in many disparate fields of medical work are lumped together as "human body fixing people". Try to perspective take on what kinds of questions they usually get and from whom they usually get them.
For a large portion of the population, there is not much will to learn deeply about things. For them, science is surface level, and not much different from faith. We still need those people to "believe" in science even if they're never going to work hard to understand it, because the human animal hasn't changed that much in the past few thousand years, and people who are curious enough today to become scientists may well have been burned at the stake as witches by the same kind of people who are reflexively dogmatic today, and those doing the burning would have felt just as justified about protecting the public safety.
I get irritated with it too sometimes, and increasingly some entities like corporations are trying too hard to turn the act of science into a PR battle. It's extremely corrosive, because a lot folks know just enough to nod their heads at something that sounds good without checking whether it's a company pushing some really flaky "science" or real, solid research.
So please, ask smart questions, but also be careful where you sow doubt. Sometimes it's better to just hit the books if you really want to know something. We're not going to reach a state any time soon where everyone that claims to love science is actually going to love the act of methodically analyzing and questioning everything. We're probably going the other direction lately.
