Olivier Roy is one of the most renowned experts on political Islam. In this interview with Michael Hesse, he talks about religious fundamentalism, Islam in Europe, and explains why the Muslim middle classes in the West ought to be recognized as a western faith community, not as an alien culture:

the modern brands of fundamentalism (wahhabism, but also protestant evangelicalism) are not the product of traditional cultures, but on the contrary the product of a crisis of traditional cultures, the product of deculturation and globalization. Religious tensions are linked with the crisis of traditional cultures, and are not their expression.
