The only evidence I present is anecdotal and I did walk out of the presentation when I couldn’t bare it anymore.
When Kenny introduced the talk he made a disclaimer that the presentation was biased and that Vincent doesn’t “necessarily” believe in the moon landing conspiracy.
The part of his presentation that I observed was poor. He started off with a history of space flight and said something along the lines of “I found an interesting point recently brought up by the conspiracy theorists that animals were sent into space before humans but animals were not sent to the moon before humans”. He left it at that.
He then goes through the list of the conspiracy claims without any analysis or the refutations as he goes along. His presentation could well go through some or all of the points afterwards with a refutation. When I challenged each claim as he brought them, he did not once indicate to me that he would get to the refutation part later.
Finally I mentioned that several of the claims were refuted by MythBusters, he immediately, and passionately, responded that MythBusters were wrong. I decided at that stage not to listen to him anymore.
And that’s my anecdotal evidence. Apparently I am outnumbered 26 to 1.
