Your replies are missing context.
So, to me, they are ambiguous. I have no clue what you are trying to say.

I think that you are trying to go off on a piece that Mr Berwick said, about how the astronauts react harshly to criticism. But this is assuming that there is not a great deal to hide, or that at any moment they may attempt suicide.

So, you attack with a "show the evidence"... If we actually met, I could literally bury you in evidence, both for and against. Then I could bury you even further with books that are not in the dichotomous camp of did we or didn't we.

If we actually want to start a discussion, we would first need to talk about which piles of evidences we need want to discuss. So that we are on the same page. That anyone might state that there is no evidence hasn't even looked.
