The other facts are not in dispute, they come directly from him or from the others involved.
The screenshot is in dispute so I would not include it if it didn't fit with the other facts.
Even if "the other facts are not in dispute" (i.e., even if everyone agrees that all those "other facts" are indeed facts), the meaning, significance, and proper interpretation & understanding of those facts are certainly in dispute.
But what is or isn't a meaningful, significant, or "proper" interpretation & understanding of those "other facts" depends entirely upon one's preferred theory or "narrative", and not at all upon those "other facts" in or of themselves. (That is because, as I previously noted, facts do not ever "speak for themselves".)
You say those "other facts" mean one thing, while others say the same facts mean something else - and no fact, in or of itself, will ever be sufficient to "prove" any of you wrong. (That is because, as I have also previously noted, "proofs" are produced by and come from theories or "narratives", not mere facts.)
This is what motivated you to say the Facebook post attributed to Anthony "fits with the rest of the facts", even though you acknowledge the disputed authenticity of the item. If the item is real, then there you go - "QED". If the item is fake, then that's just as well, too - regardless of whether you explicitly "include" it or not
[1]. Either way, it "fits with the rest of the facts" as you interpret and understand them, in terms of your preferred narrative.
I should reiterate that I am not making these observations as criticisms. Everyone does this kind of thing. It cannot be avoided. The ultimate point is simply that your stated (but not really actual) preference for "facts" as being "superior to narrative" gets things just exactly backwards. People like to indulge the notion that if they just make a presentation of "the facts" and nothing but "the facts", the puissance of those facts will somehow incontestably "prove" the desirability of
this policy over
that policy; or that Oliver Anthony is sincere, or some kind of "controlled-oppo psyop plant"; or that Trump is Orange Man Bad, or Orange Man Good; or that libertarianism (or socialism, or conservatism, or progressivism, or whatever-ism) is right and true and good, above all others. But that is just not how it works - because facts are the
servants of narratives,
not the masters.
[1] Because in this case, you deem the item to be "truthful", even if it is not "factual". This is an illustration that theoretical or narrative "truth" will
always supersede mere "facts".
