I provided it: "plausible-but-unproven accusation"

You had said "this is itself a conspiracy theory" and then provided evidence that it was false. Therefore it is simply false. But the implication seemed to be that "conspiracy theory" = "something that is false but people still believe"

My point was that, similar to many of the other "-ist"s, a term can have a technically valid meaning yet still be misused in bad faith to shut down debate. (Not at all saying that's what you were doing - just seemed like a relevant place to make the point.)
