This is sometimes called an "isolated demand for rigour"[0]. There is worldwide governmental consensus that Khashoggi was murdered. The Saudi Arabian government admits to it using purposely euphemistic language. They even had a (closed) trial and sentenced five people to death in relation to this "horrible incident."
But then, you respond, have you actually seen video footage of the murder taking place? Well, then it's settled. We truly cannot know if Khashoggi was "murdered," and since no body was recovered, for all we know he's vacationing in the Seychelles, or deep in a Turkish prison. How is this different than the "weapons of mass destruction" that got us into the Iraq War?
> You may be mistaken thinking I'm defending a government and you seem to think you're producing evidence.
This passive-aggressive nonsense is ridiculous. You seem to clinging to some fiction that SA has not literally and materially admitted to wrongdoing. You operate in a worldview where everything that doesn't meet your arbitrary standard of truth is not "evidence-based," and therefore wrong. What you present as some sort of epistemic skepticism is just garden variety solipsism.
