Islam expert Dietrich Reetz of Berlin’s Center for Modern Oriental Studies (ZMO) speaks to SPIEGEL about Muslims in Germany, social tensions and the prospects for dialogue between the communities. SPIEGEL: Mr. Reetz, recently the debate about the propensity to violence, among young Muslim men in particular, has heated up in Germany. Frankfurter Allgemeine Zeitung co-editor Frank Schirrmacher wrote that, the mixture of youth criminality and Muslim fundamentalism is the closest thing today to the deadly ideologies of the 20th century. He is drawing an analogy to fascism and Stalinism. Is that excessive dramatization or is there a real threat?
