I don't know they're a domain expert! Hence the 'heuristic' part. I do know that in the course of normal conversation I'm not owed 'links to sources'. I can certainly ask for them if I can't figure out how someone arrives at their conclusions but it doesn't make reading comments without them (or without a list of the commenter's verifiable credentials) 'outright foolish'. What you are describing doesn't sound like a general purpose forum anyone would want to participate in. And the way you're describing it sounds outright scoldish.
