Anti-immigration and anti-Islam policies are now mainstream in Europe. A few years ago, they came only from fringe groups. The Party for Freedom (pvv) in the Netherlands, Jobbik in Hungary and Future of Austria (bzö), for example, shocked politicians across the Continent, coming from nowhere, while more established parties languished.
It was a radical shift in European politics. But since then, Europe has gone through another shift, even more radical.
