Thing is all FE models absolutely rely on the conspiracy. That is no straw man, it absolutely relies on everything that could not work anywhere but a spherical Earth being a lie concocted to further the conspiracy, it absolutely relies on every space agency being part of the conspiracy. I have heard the FE hoaxers say the conspiracy is compartmentalized, I do not think they understand how that would be possible, just something they heard in relation to hiding a small conspiracy.
This is a pretty big problem, among hundreds of big problems with all those alternative Earth shape ideas. Being that the conspiracy is so large and far reaching, followers of at least this particular conspiracy theory must close their minds off to the possibility that they are mistaken. They have to ignore anything that remotely raises any small questions about their idea. They love to project their own closed mindedness onto anyone who raises questions, it has become a broken record of stupidity. In all of recorded history, whenever actual verifiable evidence that brings already held theories or ideas into question, science has reexamined and in many instances changed the theory to match the evidence.
Now take the many instances of that happening, compare it to the FE hoaxers that will give you every stupid excuse they can possibly think of to either twist or ignore anything that disagrees with their ideas. Whenever they bluster and fan out those peacock feathers, they never can answer how, and refuse to explain that the few explanations they will try to give never works with other explanations. This is where they normally disappear, deflect, or if they haven't already, start insulting.
FE, DE, and all other alternative Earth shape theories all must have this conspiracy. The conspiracy has to be very very vast. The size of the conspiracy is one huge problem with it, also among many many problems with the conspiracy.
There are just too many things wrong with the basic initial steps into thinking about FE ideas that it so quickly becomes very hard to continue to give energy to trying to give the ideas serious consideration.
