I haven't gone to bed yet so... think about what is being said: 'Same applies to anyone who kept mum on NASA's lies' is a phrase exactly like 'it could in principle be fake'. You can just keep applying it: Got the written testimony of someone who worked on progress base? They could be lying to keep mum on NASA lies. Actually take pb1985 to Progress base? How does he know the pilots didn't fly him to the arctic instead, because they're some of those who are keeping mum on NASA lies? The video clearly isn't from NASA? Well 'anyone who has kept mum on NASA lies' could also be tricking us, and given the scale of the conspiracy - literally millions of people at minimum, working day and night with apparently perfect loyalty to the conspiracy (unless anyone can point to a reliable confession) - that could be pretty much anyone. Independent/Chinese/Brazillian expedition visited the base? They were keeping mum on NASA's lies by lying themselves about where they were, and faking evidence.
It. Just. Keeps. Going - forever.
The only reason needed to doubt any evidence or testimony is that in principle it could be faked, in principle it could be made up, and it doesn't match what pb1985 has already convinced himself of - and I do believe he is genuinely convinced, at least consciously. 'They must be keeping mum on NASA secrets', and they could be anyone, and would have to be apretty significant chunk of the whole human racein fact. You know there's a kind of brilliance of imagination to this kind of thinking? And he's actually pretty eloquent. Put pb1985 in the cockpit of a plane and fly him to Antarctica, and he could claim the instrument readings were faked and the pilots were specially trained agents who were flying him back towards the Arctic. He should write spy novels!
And we're still trying to divert with the moon landings. And the personal insults come out - I'm beyond naive because I think this conspiracy is a result of his personal view of the world rather than reality, and I have poor reading comprehension because I didn't realise that, of course, 'Russia' in general would be keeping mum on NASA lies.
But, pb1985, whether you believe me or not I worry that seeing the world through this lens is going to trap you down a rabbit hole and make you miserable. I really do hope I'm wrong and you're happy, but it sounds like you literally believe the whole world is against you. Take this however you will, I really mean it, and I bear you no malice - a touch of frustration yes, but I don't mean you any harm or deception. I think our conversation is going in circles, and getting increasingly acrimonious, so I really will butt out now. Take care.
