See, I feel like there's actually much more compelling evidence for flat Earth than there is for the Tartaria theories. Whether that itself is ultimately nonsense or not is besides the point. I'm someone who is genuinely open-minded and willing to entertain the possibility that everything I've been taught is free-game. I don't think anything should be off limits as far as asking questions goes. If nothing else I find these ideas to be fun thought experiments!

That being said, I'm not just dismissing mudfloods/Tartaria out of hand because it goes against what I've been taught. I've actually looked into it myself and I just really didn't find the theory that convincing. I do think mudfloods have happened but that doesn't mean they were deliberately engineered as a planetary scale genocide or whatever. And the observation that buildings in different countries share similar styles of architecture isn't even that difficult to explain. Conventional history about Europeans borrowing their Renaissance styles from antiquity is not exactly that mind-bending.

To me this just seems like a simple occam's razor affair.
