Of course you would say that if you close your eyes and ignore the mountains of evidence that goes against your indoctrination.
I don't know about "indoctrination". That means you don't question beliefs. I think most REers do question them but actually get answers that make sense. These then become a relatively solid theory - heliocentric spherical Earth model. This can be and is taught in schools. You can call it "indoctrination" or just "common sense" supported by "mountains of evidence".
I can see why FEers can not be indoctrinated. There is nothing to indoctrinate. Every FEer has their own "theory" that is wrong. They are "free thinkers" making up stuff as they go along. What would you teach children in school?
When a child asks "where am I on Earth?", having no map, the FEer would say "after THOUSANDS of years, we still don't know. All we can be sure of is that the N.Pole is in the middle because there is an Antarctica conspiracy. We don't know distances. Although we go on ships and planes that use RE maps/globes, we don't believe in them".
If a child asks "what is the shape of the Earth?". The FEer would say "after THOUSANDS of years, we are not sure if it is a disk or plane, just that it is flat because it looks flat out my window".
If a child asks "what is the shape of the sky?", the FEer would say, "after THOUSANDS of year, we are not sure. It may be a dome, but we don't know how high it is or what it is made of. We are not sure how high the Sun or Moon are. Some people think they are flat disks, others spherical. We don't know what causes phases or eclipses. Some people believe they are Moonshramps. As today we don't use telescopes and we are really not interested in astronomy, we don't have the knowledge they had THOUSANDS of years ago."
And this what you would have us teach in schools? Really?
