Re: the specific argument about a coverup being impossible, there have been plenty of people over the years with claims like this. The idea that this guy is talking about what “a friend of a friend” said is also a very ungenerous and inaccurate claim, given the Grush’s established credentials.
Otherwise, I agree it’s hard to believe, but I don’t think this guy has actually “debunked” it as he claims in his hashtag. The options are that he’s lying or crazy, and he doesn’t seem crazy, and if he’s lying he’s going to jail. The most plausible explanation for it not being true is that it’s part of some complex psy-op, but that also is a fairly outlandish theory (albeit not as difficult to accept on its face).
I disagree with this. Definitely there are many examples of organised religion being perfect case studies of the adage that power corrupts and absolute power corrupts absolutely. But there are also many ways that religious communities support each other and their wider communities, outside just providing a doctrinal “granule of truth”.
Sikhism I think is most famous for this, and I feel like at least where I live whenever something bad happens in the background on the news I see Sikh communities mobilising to render assistance.
Similarly, the denomination I was brought up in (church of christ) has always been oriented, both in theory and practice, around doing community work first and debating doctrine a fairly distant second (also, each church of christ congregation is an independent entity, which I think has probably contributed to it being able to maintain its strong community-first focus over time).
