I don’t know if the map is accurate or not. I do know the first argument was cogent and backed up research that wasn’t rebutted or debunked it was just laughed at. The debunkers argument is based on a pathetically illogical premise and defended with grade school derisions. Apparently that’s the kind of argument that floats your boat. Go for it.
Cogent? The letter-writer was arguing that the map was drawn from information extracted when Antarctica was “very hot” and iceless, way way before any human conceived of a map. If that’s cogent and backed-up research to you, no wonder you’re sticking up for this nonsense.
