So then has anyone from FE measured this distance to determine it? Cause at first I was told that there were armed guards there. Though apparently only Diego Draw believes this meaning it shouldn't be part of FE.
That is correct. Not all FE Proponents believe in a Ice Guard Army stationed at the edges of the earth.
So then why can't you measure the distance around the Ice Wall? It should be vastly different than the circumference of Antarctica.
The Ice Wall was first discovered by Sir James Clark Ross in 1841 in search of the Southern Magnetic Pole. From his records and journals we know that the distance around the Ice Wall is considerable, stretching perpetually in every direction. Ross and his expeditionary team searched vainly for a southern passage to the Southern Magnetic Pole. In the end Ross was defeated by its vastness, returning home in defeat.
Should be pretty easy for you to prove yourselves with this don't you think?
Today the Ice Wall is open to all explorers who dare venture. In the past many Antarctic explorers have gone missing. Presumably they've gone lost and missing due to the inaccuracy of the Round Earth maps.
Feel free to commission a massive ship to Antarctica and discover the true distance around the Ice Wall for yourself.
