Besides the common community, what does this new concept have to do with flat earth? They seem orthogonal.
Also, I can set up at least half a dozen different experiments to let me "experience" that the Earth is round. Is Flat Earth Theory just another set of blinders we get to put on if we want?
As far as I can tell there's a huge overlap between flat earthers and fundamentalist religious beliefs. If you go digging into their resources you'll very often find treatises about "the science of the Bible" and similar things. As such you'll often see the same people arguing for a flat earth, intelligent design, 6000yo earth and similar things.
It's a video about how NASA supposedly fakes the Mars rover pictures, yet the description starts with "I believe the pope of Rome is Antichrist (Daniel 7:7-27,2Thessalonians 2:1-12,2Peter 2:1-22,1John 2:18-25, Revelation 13:1-9) and Rome 'Mystery Babylon the Great the Mother of Harlots and Abominations of the Earth' (Revelation 17:1-18)."
I haven't read through it but it features a chapter called "The Bible and science", an other "Moses and geologists" and a third one "science versus christianity".
I'm sure this tale of a primeval forest being destroyed by evil beings resonates with people who believe in flood myths and the like.
In the end all these conspiracy theories are about rejecting science and the "new world order/illuminatis/freemasons/..." who are the work of the devil trying to corrupt us so that we stray away from god's path, or somesuch.
