>>62679Most flat-Earthers don't actually believe that the Earth is flat. The reason the flat earth meme is spreading on the right it because the right has finally become post-modern. A big part, or even the main part of post-modernism is a skeptical view towards objective knowledge and truth.
The left became post-modern because their worldview centered equality was irreconcilable with modern biology. They believed that all people were inherently equal, but evolution, genetics, and molecular biology have disprove any notion of inherent human equality. The left chose reject the concept of objective truth, and with it science, so that they could continue to believe in human equality. This effectively drove the left insane, and is why they are willing to believe Jewish nonsense like transgenderism. Deep down, they know that they are wrong, though, otherwise they would not have needed to become post-modern.
The right, on the other hand, is becoming post-modern because of Christianity. All of modern science, archaeology, history, and basic logic and reason have thoroughly disproved Christian mythology. Without that mythology being literally true, the entire religion of Christianity has fallen apart. Liberals figured this out a long time ago and moved on. Conservatives have up until now coped by saying that parts of the Bible are metaphorical. But if the Bible is only a metaphor, then it cannot be said that it is literally true. Conservatives have reached the point that they can no longer cope with metaphors, to they are instead rejecting the concept of objective truth, and with it science, so that they can continue to believe in God and Jesus.
Flat-Earthers focus on the flat Earth specifically because the Bible makes the claim that the Earth is flat. In their minds, if the Earth is flat, and scientists could fake something so obvious as a round Earth, then all of Science and modern Cosmology must be wrong, and thus the Bible could possibly be literally true. But just like the leftists, deep down they all know that they are lying to themselves.
TL;DR flat Earthers are coping with the existentialism brought on by the death of God.
