alt Hacker NewsHave you ever called someone crazy, only for them to stop dead in their tracks and say, "wow, you're completely right, how could I have been so blind?"
I haven't, and you probably haven't, though if you have, I'd love to hear that story. As I said, they're skeptical of authority and need to run the experiment themselves; some will even flip on flat-earthers who run the experiment and change their minds. Only those who perform the experiment and still refuse to accept the outcome are deserving of being left to their own crazed devices. Until then, they're just ignorant and/or weird.
There are many, many, many examples of exactly that happening: they run experiments, the experiments prove them wrong, and they instantly declare the experiment to be wrong. You can easily find them on YouTube, IIRC a flat earth documentary on Netflix also features exactly this at the very end.
There are of course people like grifters in the community who don't believe their own words, but the believers won't reason themselves out of this position they didn't reason themselves into.
