You mention that there is no such thing as a geocentric ball theory in science, so it's interesting that Neil keeps using mainstream science to back up his views. That's why I thought he was a heliocentrist - I didn't see any obvious evidence that he was using a geo-centric model, though I may have missed it.
As you say, the ball-earthers should explain how it is that NASA has obviously lied about the fact that the earth is not a moving, rotating, barreling earth, but that NASA (they believe) is telling the truth about the earth being a globe.
What is it about NASA that inspires such confidence that they as an organization are held up as promoters of truth, even when it's shown that NASA has not been honest about other important issues? After all, NASA does not promote or even believe in God. What has NASA done to promote the idea of God, of Our Lord, or the Kingship of Christ? They've done absolutely nothing.
Yes, Neil has made a decision to fight this, but his approach as you say, is contradictory...on many
levels. (Shameless pun) The flat earth/sphere dichotomy is a huge clue to getting to the point of flat earth. We have great enemies who hate God and are intent making themselves God and enslaving us. Yet so many "God fearing men" heartily believe the enemy's false notion of creation. Belief in the devil's propaganda provides evil men tremendous power. But evil only has that power if we freely give it away by believing lies rather than God, His Word, the Church, etc. Flat earth incites the deepest of passions because we're talking about people's own little twisted world, in their own little twisted minds, who prefer a certain little twisted relationship with God based on their demonic world view. And they like it! Hence the vitriol you endure when you share the one thing they fear most: God's world, God's rules.
The true and Catholic view of our environment frees us, enlightens us, enables us to love God, worship Him with understanding, humility and awe. Not to mention, it helps protects us from becoming enslaved in a myriad of ways. It seems to me that flat earth gives us the necessary grounding we need to connect to God and to trust Him even more. It even provides a backdrop for understanding why mundane duty, maintaining simplicity, and being grounded, especially in truth, are so necessary and so good. A right understanding of our earth really does matter. Ultimately, flat earth reflects God's Word rather than the globe which puts a spin on it (pun again). God's firm, level playing-field foundation actually provides a physical basis for trusting His Word.
