As ridiculous as FE seems, prima facie, until it's proven false, I keep my mind open to plausible explanations for why:
A) the moon landings were all fake and we've never "been back"
B) there are no actual photos of the entire earth from space (unless you believe the sizes of the continents are changing by 30-60% every decade or so)
C) the only people on earth that we give billions of dollars to, to go to space, are faking any, let alone much (or all) of the footage, using green screens, parabolic "zero gravity" flights, actual hair spray to make their hair stand up, underwater studios (unless you believe in air bubbles in space)
You might say "but these items have better explanations than FE". Well let's hear those theories also. Let's not shoot down those who are proposing an outlandish, yet mostly comprehensive, theory, one that explains these anomalies as well as a plethora of others, like how did they use radio frequencies that don't even purportedly bounce off the ionosphere to communicate hundreds of miles during WWII, how can the horizon be seen above an item whose entirety should be hidden behind it, why is Antarctica, aside from a tiny portion, entirely off limits to most civilians, how was Felix Baumgartner able to slowly float up to nearly 30 miles without drifting a thousand or more miles because of the earth's rotation, etc.
Suggestions that these things are not even worthy of discussion, on a forum dedicated to conspiracy theories, have to be disingenuous.
Original Research
Let's not also forget that FE researchers are literally the only conspiracy theorists doing original research. These people will buy lasers that cost thousands of dollars, cameras, etc., and go to some large body of water (large lakes, bays, etc.) where they can test their hypothesis with an actual experiment. Everything else I see on here is pure speculation, or videos of interviews involving various professionals with dubious backstories (Malone, etc.).
Does it Matter
Pertaining the "would it even matter" argument, you honestly don't need a lukewarm IQ to imagine how much it would matter, if FE was real.
Principles
Most of us are here because we couldn't speak freely elsewhere, because "hate has no place on our platform" type communist bullshit. Now we're going to make the same kind of rules, especially banning arbitrary content that is desired by a clear majority, on a platform with already-existing mechanisms for getting rid of low quality postd (downvoting, hiding)? If FE posts are banned, this place is no better than TGA, and don't even pretend to be pro constitution when you can't even stand up for free speech about a conspiracy theory in a conspiracy theory forum.
I'm out of here, for good, if FE is banned. Aside from spam, illegal, doxxing, banning has no place on our platform.
What is malicious? Thinking something silly? Is thinking the moon is made of Blue cheese malicious? Would any of those freaking out of FE, freak the same over that? Or the Hollow Moon Base theory?
Right after 911 it was the same rhetoric when you suggested the government had some hand in it. All the same arguments and rationales. Its dumb, its stupid, we need to censor it... Why? Because it is dumb, it makes us look stupid, etc.. There were no planes, they were holograms, etc.
When "we" want to censor people - "we" become the bad guy.
Idiocy, both the conspiracy and mainstream variety, can only be fairly fought in the open, through logic, reason and rationality. When we censor people, we deprived all of us the benefit of seeing/using/observing logic, reason and rationality destroy a POV, and we are lesser because of that. IMO.
