> If you can't ever have your thing in the open maybe you shouldn't be having it at all? No matter how many gray hairs you have and how nice your suit is.
Nice in theory, but doesn't stand up to basic scrutiny. I have secrets. Hundreds of them. Mostly passwords. And I mostly keep them secret because if I don't, naughty people will take the things I need from me or generally cause chaos for me and my family.
You're absolutely right that young people are more likely to question traditional narratives, but they are less likely to have the context (or apply it, anyway) necessary to form a coherent narrative in its place, which will often lead you to at least some variation on a traditional narrative.
I think where young people often do good by questioning authority is when a traditional narrative used to apply but in recent history no longer does for some reason or another. If you're an old, you've likely already mentally examined some idea or process and found it to be sound, and now you're less likely to come back and question it later. Young people come along later and question it and find it to not be sound anymore, and the olds realize they might be right.
For most other things... You don't have to be young to smell the bullshit.
