Given that this was a 'debunking' video (and leaving aside his arguments for the mo), I thought his little bit at the end about conspiracy theorists was fairer than the usual sneering dismissal - saying we (debunkers?) should be careful when talking about conspiracies to retain scetpicism, bsically making the point that sometimes they're true; but that on the other hand there is a tendency for people to get into a habit of thinking in conspiracy theories even where there are none - and how this can be utilised from above as a way to control narratives/people. It reminded me of similar points in umberto eco's Ur facsism (or leo strauss' neoconservatism for that matter). Though this can be turned around to say other people get into the habit of thinking there are no conspiracies/nefarious purposes, even when there likely are (conicidence theorists?), and this also makes them easier to control, susceptible to confirmsation bias etc.
Whether he managed to retain the scepticism enough in the rest of the vid is another thing. (please nobody think i was characterising anyone in that waffle - maybe myself in in earlier years)
