I am not able to work out if the “Moon landing was a hoax” people really believe their nonsense or if they are just pretending to believe it.
Amongst the few I personally know that will argue for the hoaxed moon trips, it seems as though 1 in 6 do it just to mess with people. About half are true believers. And the rest are ‘skeptics’ - don’t see how we got to the moon (cue eyeroll from me), but figure there would have been deathbed confessions or other REAL evidence for the fakery to come out.
