In my new book, Porn Panic!, I recount the rise of a new British fascism. What began a few years ago, for me, as a campaign against anti-sex feminists who were trying to censor pornography, grew gradually into a realisation that free speech and other fundamental underpinnings of liberty were under fierce assault from all sides. This new authoritarian movement, which is taking over both wings of politics, has been slowly gaining ground over the past 10-15 years. But with yesterday’s Brexit vote, the way is clear for an explosive rise in fascism across Europe – and beyond.

Having stayed up most of last night to watch, with increasing incredulity, the EU referendum results, I’m still reeling. It’s not that the result was especially unexpected; but the scale of the catastrophe that is now – in real time – engulfing the UK and European economy is staggering, and dwarfs the 2008 meltdown. And if the economic fallout is massive, the political implications will be even more so. Yesterday, the British people lit the fuse. The explosions are only just beginning.

For months, most people with any understanding of what has been unfolding have just looked at each other and said “But we’d never actually vote to leave the EU, would we?”, and we’ve reassured each other that, no, when it comes to the crunch, the British people would pull back from the brink. And so this morning’s news – that the UK population voted by 52% to 48% to exit the EU – is hard to stomach.

From the perspective of the goals of my campaign, Sex & Censorship, the news is very bad. Many of the protections of free speech, net neutrality and human rights that exist in British law have been passed down to us from the EU. EU law offers a good deal of protection against the anti-sex and anti-free speech laws and regulations that I’ve campaigned against. Now, those protections risk being stripped away. The British state, restrained in many ways by the liberalising influence of the EU, may shortly get free rein to pass laws that would not have been acceptable in a western democracy during the liberal postwar era. It’s probably fair to say that yesterday, that era came to an end.

The fact that the resignation of the Prime Minister is one of the more minor stories in today’s news helps illustrate the scale of events. It’s hard to find a comparison on a historical scale. Certainly, this crisis of European politics looks to be every bit as significant as that of the 1930s. Nationalism, which has been slowly rising in Europe (as well as globally) since 9/11, has now been unleashed in a way that few living Europeans have seen in their lifetimes. The European Union has presided over the longest era of peace in European history; the British people just voted to burn it down.

The global significance of the referendum was underpinned by the fact that Donald Trump chose today to fly in and visit the UK (he quietly pre-announced the visit a few weeks ago). Trump understands the nature of fascism, and has shown a far deeper understanding of the threat to western democracy than most of the established political class. This morning, he hailed the referendum result. Simultaneously, the odds of a Trump win in November were cut sharply. Nationalism begets nationalism, and today’s Europe provides Trump with all the nationalistic sentiment he needs to further his authoritarian bandwagon. Elsewhere in Europe, fascists are celebrating. In the Netherlands, Geert Wilders celebrated the British poll and called for one to be held locally. In France, the far-right leader Marine Le Pen did the same. Those with a knowledge of WWII history will know that the Netherlands and France were deeply infected by the fascist bug in the 1930s/40s. It is not so surprising that the anti-immigrant backlash is growing rapidly in those same countries today.

Amidst the chaos, it seems churlish to ask what this means for the adult industry. But as has been so often pointed out, sex is the canary in the coalmine of liberty. Sexual and political freedoms have always gone hand-in hand; an attack on one is an attack on the other. And so surely we all – on both sides of the Atlantic – are in for a huge battle in the coming months.
