You missed a basic element of what they said: "can't measure it or repeatably demonstrate it"; seeing a non-reproducible event with your eyes is a form of measurement, and that measurement could in principle be done by an objective machine (recorded by a camera). The potential for objective evidence is what distinguishes a matter of fact from a matter of opinion.
As to the "correct formula for gravity" - that's just bad faith nitpicking. "Newtonian gravitation is a fact" is both a strawman and completely irrelevant when it comes to social media fact checkers.

No. Recording an experiment does not constitute scientific repeatability of an experiment. (Not to mention Quantum Mechanics explicitly rejects your claim as a universal principle at the micro level.)

No, it is not a strawman at all. It clearly illustrates via an example of something we have known to be false for about a century, yet not only we do not censor it on social media, we teach it to kids, and almost no one would object to it.
So, where do you draw the line?
I posit there exists facts that are unknowable by the scientific method. The GP claimed science as the end-all-be-all method to fact-check. My statement is that it's not sound, nor complete, in its ability to fact-check.
