Since September 11, Western governments have legitimized and empowered "nonviolent Islamists" as representatives of Islam for all Muslims in the West, an approach that has worried Muslim moderates.  Citizen Islam addresses the implications of this approach.

The book opens with an overview of the theology and history of Islam, to show that violence and intolerance are not fundamental aspects of the religion. It then explains the growth of Islamism in Europe and in the United States before suggesting that both are finally beginning to recognize the threat posed by nonviolent Islamists. Lastly, it outlines steps that Western and Muslims leaders can take to strengthen moderate Islam and counter the threat of Islamism.

Written by Zeyno Baran, a Turkish-born Muslim, Citizen Islam sheds a sharp light on Muslim communities in the West. It concludes that there is much that Western governments can still do to reverse the spread of Islamism. But they must act quickly.
