Let's take a step back and recall how Donald Tusk, president of the European Council, warned that Brexit, “could be the beginning of the destruction of not only the EU but Western political civilization in its entirety”.
The barbarian hoards are at the gates!
Eurasia Group President Ian Bremmer said the Brexit is “the most significant political risk the world has experienced since the Cuban Missile Crisis.”
Nuclear holocaust!
David Cameron told us the consequences for ignoring their advice.

Protections for state pensions, the NHS and defence spending cannot be guaranteed if Britain leaves the EU.

Rivers of blood! Fire from the sky! Plagues of locust!
Do you get the picture?

But you foolish mortals didn't head our warnings. Now look at the destruction you have brought down upon your heads!

The Bank of England has yet to see evidence of a sharp economic slowing, even after U.K. businesses said the vote to leave the European Union had caught them by surprise.
While uncertainty rose “markedly” after the June 23 referendum, most firms did not expect to alter their investment or hiring plans in the near term, according to the BOE’s Agents’ summary of business conditions, based on information from a network of representatives across the U.K.

Hmmm. OK. Not exactly the destruction of Western political civilization in its entirety, but it's still coming! Our destruction train is just slow getting out of the station. Our neoliberal masters wouldn't lie to us!
Right?

IMF officials were labelled ‘clowns’ with ‘serious credibility problems’ last night after saying the British economy will grow faster than Germany and France in the next two years – only weeks after its doom-laden warnings about Brexit.
After saying that leaving the European Union could trigger a UK recession, the International Monetary Fund now expects the British economy to grow by 1.7 per cent this year and 1.3 per cent next year.

Seriously? We've gone from Brexit would be ‘pretty bad, to very, very bad’ for the UK to "the second-fastest growing economy in the Group of Seven industrialised nations this year" in just a couple weeks?
This is what "doom" looks like?

No, wait. This is what "doom" looks like.

U.K. stocks climbed Wednesday, sending the FTSE 100 to its highest close since August last year, aided by gains in insurers.
The benchmark is up almost 8% year to date.
“We’re seeing quite an incredible rise in equities right now. One of the better sectors out of the U.K. has been exporters, strictly playing off of the pound post-Brexit, leading to quite a good scenario in the short-term,” for such companies, said Adam Karrlsson-Willis, vice president of equity trading at INTL FCStone Financial.

Whoa unto post-Brexit Britain as they suffer the burdens of rising stock and export markets.

“It’s good for the markets to see that it seems as though ... people are actually sitting down and trying to make [Brexit] work appropriately for the economy and that’s probably why you’re seeing a good, decent boost to equity markets right now,” Karrlsson-Willis said.

OK. So Brexit might mean prosperity for Britain, but its still bad because it was driven by ignorance and racism, right? That's all you have to know.

The well-to-do voted Remain, the down-at-heel demanded to Leave. The Brexiteer/Remainer divide splits almost perfectly, and beautifully, along class lines. Of local authorities that have a high number of manufacturing jobs, a whopping 86 per cent voted Leave. Of those bits of Britain with low manufacturing, only 42 per cent did so. Of local authorities with average house prices of less than £282,000, 79 per cent voted Leave; where house prices are above that figure, just 28 per cent did so. Of the 240 local authorities that have low education levels — i.e. more than a quarter of adults do not have five A to Cs at GCSE — 83 per cent voted Leave. Then there’s pay, the basic gauge of one’s place in the pecking order: 77 per cent of local authorities in which lots of people earn a low wage (of less than £23,000) voted Leave, compared with only 35 per cent of areas with decent pay packets....
Surveys, however, dent this claim that the anti-EU throng was driven by disdain for foreigners. In a post-vote ComRes poll, only 34 per cent of Leave voters cited concern about immigration as their main reason for voting out (and concern about immigration isn’t necessarily racism). A majority, 53 per cent, said they rejected the EU because they think Britain should make its own laws. So this swath of the country, defamed as a brainless pogrom-in-waiting, was actually voting for democracy

Oh, yeah. Class, the one thing the neoliberals in the Democratic and Labour parties pretend doesn't exist anymore, and democracy, the thing the neoliberals in the Democratic and Labour parties pretend to still respect.

Distrusting and rejecting popular will has always been the domain of the wealthy, right-wing elite until now. And for what? Is fighting a initiative, supported by the working class and rejected by the globalist financial elite, really something you want to sacrifice a sacred value for?
You can't come back from rejecting democracy. You can't pick and chose what you will accept and call it democracy.

Or as Matt Taibbi put it:

My admittedly primitive understanding of democracy is that we're supposed to move toward it, not away from it, in a moment of crisis....
If you think there's ever such a thing as "too much democracy," you probably never believed in it in the first place. And even low-Information voters can sense it.

A good example of this "new progressive" side can be found in this New Yorker article, called "A Perilous Nationalism at Brexit".
Now I've never been a fan of nationalism, but I find it ironic that these liberals can be threatened by nationalism when people vote against Globalism, as Obama said. Yet they don't see the dangers of nationalism when it comes to hyping it for war.
Bernie Sanders gets it.

Surprise, surprise. Workers in Britain, many of whom have seen a decline in their standard of living while the very rich in their country have become much richer, have turned their backs on the European Union and a globalized economy that is failing them and their children.
