Consider this case, hot off the presses. Yesterday Aaron Sorken wrote an open letter to Mark Zuckerberg in the New York Times in which he stated the following:
"And right now, on your website, is an ad claiming that Joe Biden gave the Ukrainian attorney general a billion dollars not to investigate his son. Every square inch of that is a lie and it’s under your logo. That’s not defending free speech, Mark, that’s assaulting truth."
Really? Sorken knows for sure that Biden was not self-dealing? Joe was totally not thinking about his son's half million dollar no-show job with a corrupt Ukranian firm when he ordered the Ukranian government to fire the guy who was investigating it? Wow, that's a really amazing level of access to the truth!
No doubt Sorken has heard and completely believes the mainstream narrative: the prosecutor was himself corrupt and all right-thinking people wanted him removed. (Never mind it's entirely possible that this narrative is true, AND Biden was self-dealing.)
My point is not to convince anyone that Biden was self-dealing. My point is that Sorken is calling objectively false something that is clearly plausible.
This is how it goes. Most people are invested in narratives, and they are keen to suppress ideas that counter their preferred narrative. The idea that they will somehow draw clean lines between facts an interpretations has always been a foolish hope.
