What this episode also exemplified was how whenever these realities emerged it turned out that they had been warned of before the Referendum and dismissed by Brexiters as Project Fear. Yet, inevitably, their emergence did not lead the Brexiters to admit they had been wrong but, rather, to insist ever more angrily that they were right. Indeed, worse than that, by configuring each consequence as a punishment they ‘proved’ that the EU was a malign body and therefore validated the decision to leave.
I have an emotionally abusive family member who is never, ever responsible for the consequences of their actions, so I saw this coming a mile off. (No idea how Family Member voted: I just recognise the behaviour.)
If Family Member wants to do something, there's absolutely no telling them that water is wet and gravity acts downwards. All that trying to warn them gets you, is the blame when FM finds out the hard way.
FM is completely un-selfaware and will actively go round canvassing validation from their friends: "So-n-so said it would get wet – so she must be the one who wet it!!!"
FM responds to flattery and to Happy Feelz. They can also be kept in check by fear of public shame, but that's always risky: FM needs a Good Feelz escape route to divert into, because you must never, ever, trap FM in a corner. They'll burn everything down rather than face responsibility for Bad Stuff.
In order to change course, FM needs someone else to blame. It might be someone who failed to give them a key piece of information, or lied to them, or failed to complete a task. So in good news, you can feed FM a carefully chosen (and safely out-of-the-way!) scapegoat to help them dig themselves out of their self-made hole.
NB, FM's ire to the scapegoat is in proportion to their need to escape blame themselves – so IMO it does have to be either someone who bears some responsibility, or someone who's safe from harm.
(This post comes with the usual carpe lector that it is not about people who voted Leave per se; it's about people Farage who have those behaviours, however they voted.)
