Dave,
Maybe we can take this discussion down a different course. Let's see what we can find as common ground. I know you're not much into astronomy and related sciences but since the shape of the planet is, at its core, an astronomical issue, I think it might be beneficial to ask you just what astronomical ideas you do accept as true.
Do you, for example, accept that Jupiter is a planet and that is has at least four moons that orbit it?
Do you accept that Saturn exists and that it has actual rings that surround it?
Do Sun spots exist?
I ask these specific things because they are all things that anyone can see for themselves with even the most modest equipment. Galileo saw the moons of Jupiter with a telescope that would be outclassed by modern telescopes that you can buy for less than 50 bucks. I've looked at Jupiter and it's moons multiple times this week with my 8-inch reflector that Galileo would have murdered be with a spoon to get one look at.
So, I'm wondering if you acknowledge what normal everyday people (i.e. not NASA scientists or government agents) see for themselves.
