This post is a must read from John A. Azumah at First Things:
The world is being subjected to horrific images of religious violence. The Islamic State (IS) in Iraq and Syria records its beheadings. Boko Haram in Nigeria parades hundreds of kidnapped schoolgirls. Al-Shabaab in Somalia attacks a shopping mall in Nairobi. These barbaric acts can make us feel helpless, fearful, angry, and even guilty, because there seems to be little we can do to stop them. Meanwhile, commentators traipse from one television channel to the other, presenting their analyses. Some condemn IS and Boko Haram but assure viewers that their acts have nothing to do with true Islam. Others opine that IS and Boko Haram do represent Islam's true face. Neither perspective is helpful. Both distort the nature of Islam and its relation to terrorism and violence.
It is... simplistic if not misleading to argue that groups like IS and Boko Haram have nothing to do with Islam.
Nevertheless, it is equally misleading to argue that the jihadi groups represent the true face of Islam.
