RationalWiki defines the phrase "Just Asking Questions" as:
Just asking questions (JAQ-ing off) is a way of attempting to make wild accusations acceptable (and hopefully not legally actionable) by framing them as questions rather than statements. It shifts the burden of proof to one's opponent — rather than laboriously having to prove that all politicians are reptoid scum, one can pull out one single odd piece of evidence and force the opponent to explain why the evidence is wrong.
It should be noted that accusing one's opponent of "just asking questions" is a common derailment tactic and a way of poisoning the well. Asking questions in and of itself is NOT invalid.
Occasionally, we get references to articles that use this technique to strongly suggest that there are questionable aspects about an issue without openly making a claim - e.g. that someone is corrupt.
How should we deal with questions that rely on such articles? Should we disallow them, as there is no specific claim? Should we allow them as they are evidence that people believe that the open speculations are true?
