I don't recall, since the departure of Patrick1000/fattydash/DoctorTea/etc., that anyone has impugned anyone else's credentials. (P1k/fd/DT/etc. continually contradicted his
own resume claims, so he was unquestionably lying even before addressing his manifest deficiencies in various areas.)
As far as I can tell, FF88 isn't claiming any particular expertise - I've certainly said he has no relevant expertise, and invited him to correct that characterization. Nor, AFAIK, has he tried to say, for example, I don't have the credentials I claim.
What he
has done is try to say that every expert who disagrees with him is lying. I called him on it, and he finally
conceded the point by failing to provide any evidence for his claim. So I've moved on, and will ignore any attempts by him to try to resurrect that particular accusation - unless he actually offers some evidence to back it up.
Speaking of which, FatFreddy88, why do you think someone like me, with quite a bit of relevant expertise, disagrees with someone like you, with no relevant expertise? What does that tell you, that I both understand space flight
and I believe Apollo really happened? Put aside your reflexive denial for a minute and
think.
