After the first few minutes, I didn't bother following that load of utter bollocks, because it was quickly apparent who the intended audience was, and it wasn't me.
If I'm going to credit DC with any remaining Rasputin-esque intrigue, I'd suggest that his statement was aimed squarely at the [419 letter victim / snake-handling-cultists / KoolAid drinking] demographic.
Anyone recall, many moons ago, I wondered if continuing Brexit-adoration with all its mutually-contradictory oxymoronic empty-slogan nonsensical fact-free fervency was a modern secular psychological manifestation of the Costly Signalling Theory?
This originated from evolutionary biology, the basic idea being that an individual could signal their superior fitness by some expensive apparently maladaptive flamboyance - e.g. the peacock's tail - the pay-off being that they would be more reproductively successful. In human psychology, the analogy was that an individual could signal their fervent allegiance to their group by undertaking ostentatious maladaptive behaviours and psychological burdens - e.g. extreme forms of religious worship, affirmation of fantastical beliefs in the face of reality - the internal pay-off being the rewarding feeling of belonging, externally the acceptance of the group, and in our evolutionary past, better chances of survival due to this (but not anymore,, looking at modern examples such as TWAW, Flat-Earthism, anti-vaxxing, Brexitism and COVIDiots).
Anyway, this is a long way of getting back to my point: DC's complete corned-beef hash performance, if there had been any design behind it at all, is aimed at shoring up the support of the particular subset of the population who have completely wedded themselves into a Brexit=Tories=Boris=AllBrexiteers=Cummings=Great=NeverWrongNoMatterWhat identity. The story is deliberately costly. Just imagine the psychological reward of utter warm cuddly group belonging, at wholeheartedly believing that it's reasonable to drive your wife and child 30 miles whilst visually impaired specifically in order to test your eyesight.
