This is such a bad, cheap philosophical argument, I cannot think you really want to fight about it. Was Jackofhearts swindled into saying a mathematically inexact statement? The answer is... Who cares???
The representation of the surface of spheres in flat maps is reasonably precise and well understood (even though it is not perfect), The representation of of flat "planets" in a map is easier still. We are not interested in little word games about this, we are interested in the humongous problems that every "flat Earth map" has.
Which is what we're currently discussing. If you followed the thread carefully, you'd know as much.
Summary:
1. Round Earth maps are perfect.
2. It is impossible to make a perfect flat map of a spherical Earth.
3. Therefore FE is impossible.
I believe you can see what the problems of this track of thought are.
This is what we're currently discussing, and that is why the answer is
not "Who cares???". It's actually very relevant, because the "inexact" statement
is the topic at hand.
And he wasn't swindled into saying an inexact statement. He was, and is, using something entirely incorrect as a proof of the Round Earth. What he doesn't notice is that, by doing so, he is actually attacking RET. Therefore, I am defending both theories from his statements.
However, I am glad that at you understand that his statement is inexact. I was slowly beginning to have my doubts, seeing how confident he seems.
Allow me to illustrate a similar, yet not identical situation (note: this is not entirely serious, which means it is not supposed to be taken as entirely serious. It is an illustrative illustration, the point of which is to illustrate a phenomenon):
Step I: A claim of perfection of an unrelated thing:
The current understanding of DNA is perfect.
Step II: An "inexact" statement:
Okay, so, as we all know, F=m*v+s
Step III: A statement contradictory to the second one, supposedly drawn as a conclusion of the first two:
AND THAT'S WHY F=am!!!!!
