For whatever it's worth, I think we're past the point where anything constructive can come from this thread. When someone is absolutely certain that the world is flat and has invested themselves in that narrative, even well-constructed rhetoric and tangible evidence to the contrary is not enough to sway them. The same phenomenon is at play here.

And in fact, evidence shows that such counterarguments are more likely to strengthen a person's resolve in their viewpoints. This is called the Backfire Effect.

So I guess it comes down to what any given poster wants is hoping to get out of this. If you just want to argue back and forth because something about that satisfies you, sure, go for it. But if you're looking to actually change minds, further engagement is far more likely to have the opposite effect.
