It is somewhat comforting to observe that all scientific arguments about the flat earth hoax have been replaced by historical arguments, as in "he said this, no because she said that, but he is more reliable, and she's more trustworthy, but my source is better than yours, and you don't understand what he said that she claimed that they denied...".
At least these historical arguments are not clear cut like the scientific evidence we can all verify for ourselves. So, we can now argue indefinitely, and nobody will ever have to admit defeat. Yeepeeyaeyee, a happy medium !!
