One narrative about Muslim immigrants in Europe is that only a relatively small proportion holds views that are sometimes labeled as "fundamentalist." Ruud Koopmans from the Wissenschaftszentrum in Berlin argues that this perspective is incorrect. He conducted a telephone survey of 9,000 respondents in the Netherlands, Germany, Belgium, France, Austria, and Sweden and interviewed both Turkish and Moroccan immigrants as well as a comparison group of Christians.
His first finding is that majorities of Muslim immigrants believe that there is only one interpretation of the Koran possible to which every Muslim should stick (75 percent), and that religious rules are more important than the laws of the country in which they live (65 percent). Moreover, these views are as widespread among younger Muslims as among older generations.
He then looks at hostility toward out-groups. Fifty-eight percent do not want homosexual friends, 45 percent think that Jews cannot be trusted, and 54 percent believe that the West is out to destroy Muslim culture. Among Christians, 23 percent believe that Muslims are out to destroy Western culture. Koopmans says these results hold when you control for the varying socio-economic characteristics of these groups (although the analyses are not presented).
