There's a bit of a problem here with the definition of the word "debunker". If we take it to mean "anyone who doesn't support the truth movement", then bill smith would have a valid argument, because people who don't support the truth movement make up the vast and overwhelming majority of the population, and therefore almost certainly can account for more than five murders. However, that's perhaps not a line of argument bill would like to emphasise. If we define "debunker" to mean "someone who actively argues against the truth movement", then there's a rather bigger problem for bill smith, because any murder by a debunker would have been seized on so quickly by the truth movement that we'd hardly have failed to hear of it. Of course, there's the usual truther hyperbole by which any and all deaths in Iraq are described as murder by the US Government, and the US Government is included in the definition of debunkers; but then, if bill had meant that, he'd hardly be saying that he can't back up his vague accusation. So that can't be it, and we can exclude deaths due to the actions of the US Government. Who does that leave as the definition of debunkers? Why, us, on this forum, of course.
Therefore: Bill, you've accused a movement, one largely defined as a subset of the past and current membership of this forum, of murdering six or more people. Please provide (a) evidence, or (b) an apology.
