But when you go out and try to spread your gospel that the earth is triangular then people will correctly tell you to shut up and read some books before arguing further.

So can I tell you "shut up and consult some geodesic models" when you spread the gospel that Earth is round?

Because strictly and Mathematically speaking, Earth is NOT round. It's NOT spherical or oblate either.

Why do you selectively reject some approximations (models!), but accept others?
