Perhaps the lesson in this is the folly of referendums in post-factual democracies.
I don't think so. I don't even know what you mean by "post-factual democracy" and will file that in "words and phrases never to use unless I want to appear pretentious" along with "neoliberal".
The British people decided on a democratic process to decide a very important constitutional matter. A good proportion of them voted on it. A majority of those who voted want to walk back from being controlled by an undemocratic multinational structure. Now we just have to hope that a good way can be found to turn that democratic will into a practical solution.
It simply means that voters made decisions based on lies. I guess some very cynical people trying to justify that it got the result they always wanted will claim "but that's how it always works", as politicians have always been rather good at presenting facts in a manner that suits their agenda, but when they tell blatant lies, then media have played their part in uncovering the lies. Not any more.
The media is now more partisan than it's ever been - in a shrinking market for advertising then they're not going to upset the demographic that they're targeting by telling people things that they don't want to hear. Don't kid yourself that I'm "making this up" You see exactly the same divisions here in NZ on TV "news and current affairs", petitions to sack Hosking on one side, protests to reinstate Campbell on the other.
Britain will be better off post Brexit? How's that looking? Was that ever credible - or a pack of lies. How is the presidential selection process going on in the USA? What are the "issues" driving opinion? Are they "real" or a pack of lies? 30,000 Americans a year dying at the muzzle end of guns, and Islam is America's greatest threat, Mexicans are taking away jobs, and Obamacare means that government is going to start euthanising old people.
You can choose not to use the term, I think it's succinct and not a made-up deliberate insult like "bankster" and will continue to use it. If you think that's pretentious of me - that's your problem.
