No one has addressed the fact that maps of FE and RE differ in layout, continent shape and distance. Its obvious that they do because a map of Flat Earth should portray EXACTLY how the continents look and are placed as the distortion in RE maps comes from trying to portray a round object on a flat projection.
For obvious reasons, FE doesn't have that problem. However, since FE'ers often think obvious things are incredibly difficult I'm going to spell it out: Flat Earth maps are a flat projection of a flat object and should be a perfect representation, whereas most RE maps are distorted (I'm going to find a link to a RE map which has very little distortion to show the obvious difference between the maps.)
Sextants work with a RE map, which is drastically different from an FE map. EVEN IF Sextants work with bendy light, they should not work on a RE map if FET is correct.
But they do.
Now please provide counter-evidence to this, and PLEASE STOP ARGUING OVER HOW BENDY LIGHT WOULD AFFECT SEXTANTS.
Willmore and I settled in a civilized fashion that RE'ers need to prove that bendy light would effect sextant usage before that point can be argued further. So quit arguing about it, because its a dead issue.
