FES members talk about using principles like the Zetetic method which is an empirical and scientific question and answer approach, but then they subscribe to believing in hoaxes which is the total opposite approach as the Zetetic method intended.
Sure, if we just claimed a hoax and cited nothing to support it, you might have a point. But that is not what we have been doing.
You kinda have. You have a few links in the Wiki to some conspiracy nonsense, but when Elon Musk shot a car into space I saw no-one offer any evidence that it was faked.
Rather you seem to fall back on this reasoning
https://wiki.tfes.org/Place_of_the_Conspiracy_in_FETP1) If personally unverifiable evidence contradicts an obvious truth then the evidence is fabricated
P2) The Flat Earth is an obvious truth
So, according to you it's obvious the earth is flat ergo Musk's launch must have been fake. No evidence provided or required.
This is not rational thinking, one should always be prepared to alter one's opinions in the light of new evidence.
If I see David Copperfield flying in a magic show then I might not be able to see a wire but my experience is that
a) Magic shows are about being tricked and
b) People can't fly
So I can fairly confidently assume that there is a wire or something supporting him. I don't change my views on whether people can fly or not. If someone shoots a car into space then if I believe that space travel is not possible then my immediate reaction may be that it's fake. But if that person has a history of customers who have paid him to shoot other things into space, and has a queue of other customers waiting for him to do so. If I notice that my GPS and satellite TV work, I'm shown evidence that the ISS can be seen from earth. As more and more evidence builds that actually we do now have the technology to shoot stuff into space it becomes more and more irrational to dig my heels in and claim it's all fake with no basis.
How you arrive at P2 remains a mystery to me. A flat earth is arguably the simplest conclusion if you understood nothing about the way the world works, just look out to sea and observe a horizon which appears flat (note the "appears" and consider the limits in our visual accuity). But as someone else noted, even the ancients wouldn't have thought that the sun was circling above a flat plane. The simplest conclusion would be that the sun is circling above and below a flat plane, they probably thought that when it was night it was dark everywhere on earth. Now we know better.
Your circling sun with its change in orbit to create the seasons and change in height to create moon phases is all rationalisation. It's a fudge which you try to use to explain observations but it fails on many levels. It cannot explain the observations of sunlight hours in the southern hemisphere, much less 24 hour sunlight in Antarctica. It cannot explain the consistent size of the sun (so you rationalise again and make up another fudge, some magnification thing). It cannot explain sunset (so you rationalise again and make up some new rule of perspective which attempts to explain how a the gap between a sun THREE THOUSAND MILES above the earth cannot be seen and the disc is observed to sink slowly behind the horizon). It cannot explain the consistent angular speed of the sun over the course of the day - I haven't heard a response to that one yet. Your model fails, it does not match empirical observations - something you claim to think important. And yet you don't change your model or opinion. Odd.
