..so just challenge them when confronted. Flat earth stuff is intelectual inquiry and not a loaded question like your example about squirrels. It can be easily proved wrong, so just do it.
You've obviously never tried to confront a flat-earther or their kin. You should try it some time. It's enlightening and scary and every bit as emotionally fraught as my example. And when you get to the climate-change deniers and the holocaust deniers, it stops being funny too.
You obviously neither know what the backfire effect is nor why you should engage in open debates, anyway. I've talked to people believing in god before, so I know what it's like to talk to a wall. And I've talked to flat-earthers. They are fun and have interesting arguments that nicely intersect with the NASA conspiracy nerds. I came to the realization that I don't know enough about earth to counter the arguments of the flat earthers. Same with the holocaust deniers, really. But the debates were interesting and I gained new perspectives. Climate change stuff on the other hand I've never debated anyone about, since I already know that I know nothing about how this is supposed to work. No idea why CO2 is bad or why it's bad that it gets warmer a few degrees. I wouldn't mind it getting warmer. Maybe the South Pole would become a continent people can live, then. Not that I have noticed any climate change the past couple of decades I've been alive. Highest temperatures I remember are from over twenty years ago, which was about 44°C. Nowadays the hottest I recall are like 38°C. But then they changed the term from global warming to climate change for a reason, I guess.
