In fact, on the whole, people are relatively calm in the Netherlands. But there is indeed something a little frenzied about the new populism, exemplified by Geert Wilders, just as there was something overexcited about the social changes in the 1960s: sex, drugs and rock 'n' roll as a reaction to centuries of dull Calvinism. Long periods of calm, then, occasionally interrupted by bouts of hysteria.
