That's it Tom? The guy rips your world apart, and you come back with, well that crap map no longer stands, some other loony came up with another crap map, let's just ignore the rest?
The bi-polar model replaced the mono-pole model in the Flat Earth Society of the early 1900's (then called the Universal Zetetic Society). The author of Sea Earth Globe was the also primary editor of Earth Not a Globe Review, the Flat Earth research journal that continued Rowbotham's research. That society died off during World War I and subsequent reboots of the society were based on Rowbotham's original Earth Not a Globe. Few copies of Sea Earth Globe or ENAG Review were available. It is only relatively recently that those other works were found in an obscure section of a British library and digitized online.
Most people still use the old map, but that is just because they are unaware of the research that happened after Rowbotham.
Yes, so often we find some flat-earthers swearing black and blue that Antarctica is inaccessible, that we are stupid to talk about a South Pole and lying (yes, I have been accused of thst) to claim that we can see the rotation of stars about the South Celestial Pole.
Then when we try to give evidence for these things we again told not to be stupid, "That''s not the official map!"
There is no such thing as "The Flat Earth"! It seems as though there is a different flat earth model dragged out to suit the occasion!
I know of three or more "maps" (continental layouts) and three or more different explanations for gravity - though not on this site.
But how is any newcomer meant to sort this out? The Wiki says
Circumnavigation
The Flat Earth is laid out like a North-Azimuthal projection.
The North Pole is at the center while Antarctica is at the rim. The continents are spread out around the North Pole.
It really does seem a case of "Would the real flat earth please stand up!"
