Do "flat-earthers" attempt to sail around the world to prove their theory? Would this support their belief in a flat Earth?

A Colorado pastor just paid to bring some flat earthers and globe earthers to see the 24 hour sun in Antarctica. People with flat earth channels. At least one of them admitted that there really is a 24 hour sun in Antartica. Some flat earthers said the existence of this would disprove flat earth. Now flat earthers are spamming all sorts of reasons why either this whole trip was fake, or that a 24 hour sun doesn’t disprove a flat earth.

Long story short, no evidence has changed some flat earthers public position on flat earth.

Sad, really sad. And frustrating. What is wrong with people, I keep having to ask?

If they are honest flat earthers, and not total muppets, it’s hard to understand how they can keep failing to weigh the evidence against flat earth. Which may imply it comes down to some sort of faith gripped tight in their hands, refusing to let go.

Is it that their brains are incapable of rational appraisal of information and a desire to get to the truth by making the best informed decision they can?

Is it because they are trolls and not really flat earthers?

Will, probably nothing, we knew this was going to happen.

But in the face of compelling evidence, there are flat earthers who will reject it.
