They're busy oppressing minorities for the government.

The Final Experiment in Antarctica about a year ago fractured the community. The way this sort of thing generally works is that a lot of them break off, but the remaining ones are even crazier than before. As examples, see the Great Disappointment among Adventists, or 1975 among Jehovah's Witnesses.

That said, they still lost some major voices. If you don't follow this sort of thing on YouTube a lot, you're probably going to miss them completely.

no offense but the world clearly revolves around the north pole, not the south pole.

but that is already 1 too many for a flat earth

You can do this same sort of thing in the Northern Hemisphere. It just gets more obvious the further you go south.

For example, check a direct flight from LA to Seoul. On a Gleason map (the most common flat earth map, though there are a few others), flights between those two should be going well over Alaska and parts of Russia. On a great circle route, they barely go over the Aleutians and don't go into Russian airspace at all. Guess which one flights actually use?

Is there one that isn’t nonstop (excluding stopovers in New Zealand- not because it doesn’t count, but because I’m wondering whether there’s a place to stop between South America and Oceania)?

There's a few different solutions. They tend to invent brand new physics in the course of explaining it.

trick question: they don't think.

but if you want to know how they say the sun works, it is a combination of light having a limited range and some weird thing about angles that they use to justify sunrises and sunsets

Spotlight above the north pole that spins around and lights up different parts of the world at different times, obviously. Why doesn't the Sun appear from a northern angle when it's pointed at you in the daytime? Shut up round earth shill, nananana I can't hear you!

Think?

What’s an Australia? Is that like one of those New Zealand’s?

On a globe, yes. If the earth were flat as depicted in the above map with Antarctica as the edge then no. This simply points out one of the many illogical points to flat earth conspiracies.

There's a rule that the flight has to be within so many minutes of a diversion airport at all times, and this is hard to do in Antarctica.

Nowadays, 180 minutes is fairly common, and there are some planes and airlines that can go to 240 or even as high as 370.

Depends on which side of the flat Earth you are on
