even if someone had a picture of themselves with an ice wall sniper on the top of the "gigantic wall of ice no one has noticed yet", the Fe'ers wouldn't accept it.
Acutually, neither would I, because the earth is round.
Antarctica is a huge 'red herring' when it comes to Flat/Round Earth debate, I think, because it is so isolated whichever model you adhere to.
For a looooong time I and a few other Round Earthers tried to use the Antactic "midnight sun" as an argument (over on the .net site) why Antarctica *had* to be at the bottom of a global Earth
(*) ...
(If Antactica is a ring of ice around a big Flat earth then The Sun has to disappear over to the other side for at least half of every day.)
But the Flat Earthers just either:
Dimissed out of hand our 'proof' - always second hand at best - as lies perpetrated by 'The Great Round Earth Conspiracy'
Or made up arguments about The Sun's image reflecting off ice crystals from one side of the disc to other.
Whilst the latter is patently ludicrous to most people. we couldn't prove it because we could not go to Antarctica.
Edit 2: and no Flat Earther would want to mount an expedition to Antactica to gather their own data because they don't want to be killed by the guards that The Conspiracy place there. (That's a *lot* of Antactic coastline and a *lot* of guards - but it's still true, apparently.)Any proof of a Round Earth has to be based on what we can see or do where we are because Flat Earthers tend to dismiss second or third hand accounts as lies.
But even then a sufficiently zealous Flat Earther is never going to admit defeat ... but it's fun trying!
(*) Edit - here is a link to one of the later "midnight sun" threads which links to previous ones:http://theflatearthsociety.net/forum/index.php?PHPSESSID=50baccb19e8f002dd230774453ea5918&topic=526.0The debate could be described as a draw at best ...
