Moderate Muslims Exist; Moderate Islam Does Not
Robert Spencer at Jihadwatch:

Johnson here confuses moderate Islam with moderate Muslims. In Ibn Warraq's lapidary formulation, there are many moderate Muslims, but no moderate Islam. In other words, there is no traditional, mainstream sect of Islam or school of Islamic jurisprudence that does not teach warfare against and the subjugation of unbelievers. But that doesn't mean that every Muslim is with that program, any more than Jesus' teaching means that every Christian turns the other cheek and loves his enemies.

More from The JPost, from Tawfik Hamid. Who is Hamid? A guy who'd know:

The writer is an Islamic thinker and reformer, and a one-time Islamic extremist from Egypt. He was a member of the terrorist organization JI with Dr. Ayman al-Zawahiri, who later became the second-in-command of al-Qaida. He is currently a senior fellow and chairman of the study of Islamic radicalism at the Potomac Institute for Policy Studies. www.tawfikhamid.com

His words on Islam:

Saying that "Islam is the religion of Peace" or condemning the IS as being "un-Islamic" without condemning the principle that Muslims must fight non-Muslims to subjugate them to Islam is not just hypocritical but also counterproductive as it hides the true cause of the problem and impedes the efforts to solve it. Similarly, not calling the IS the Islamic State (to avoid using the word Islamic)--as suggested by some Islamic scholars--is not going to change the painful fact that the IS is using an approved and unchallenged principle of the Islamic theology. Such scholars need to work on providing peaceful alternatives to the current violent theology instead of asking the world not to call the IS the Islamic State. In brief, there are certainly many moderate "Muslims." Until the leading Islamic scholars provide a peaceful theology that clearly contradicts the violent views of the IS, however, the existence of a "moderate Islam" must be questioned.
