This is actually a huge pet peeve of mine; when people ask for a citation for reasoning, and then smugly declaring victory when no such citation is provided, as if you even could "cite" analysis.
It seems like being clear about what you're doing (are you just discussing possibilities or trying to claim something specific) would go a long way in avoiding such misunderstandings.
(And I of course don't know which cases you're talking about, so I'm just talking about possibilities.)
