Seriously, Neil, do you not get that showing one thing to be fake only ever shows that the one thing is fake? It doesn't matter if it's the PLSS relative to the whole of Apollo or Apollo relative to 9/11. In order to show the entire record to be fake, you have to go through every piece of evidence. Let's for a moment posit that, okay, the PLSS was fake. What does that prove? I can think of a couple of possibilities without even trying.
1. The astronauts were in fact cooled with technology that is for some reason classified.
2. The astronauts weren't cooled. (We know from anecdotal evidence that this isn't true, and I believe it medically can't be true, but never mind.)
So okay. You want to move on and prove that all of Apollo was faked? You must start proving that other aspects were faked. Because the PLSS being fake doesn't do anything to wave away the literally tons of other evidence.
But sure, why not? Let's say you are the first person ever with a coherent story that explains literally all of the evidence. I can't even come up with an imaginary explanation that handles it, but whatever. You somehow do. You know what? That still proves nothing about 9/11! No, seriously. You have to start the process over with every single piece of evidence there. Every piece of evidence stands on its own. The late Vincent Bugliosi used to say that evidence was not a chain. It was a rope. You didn't destroy it by destroying a single piece, because all the rest of it was still binding.
