Religious extremists want to show us that the only possibility is for us to kill each other, so September 11 is not only heinous murder, it is also global performance. It is also putting an idea into the world, an idea of destruction.

Finding Mecca in America weaves social theory and concrete ethnography into a significant contribution on Muslims in the United States, illuminating broader questions about the integration of minority and immigrant groups along the way. This is an important work and a joy to read.

I think that we live in a remarkably networked world. The problem with that, of course, is that tensions can travel in nanoseconds across the Internet, and so the tensions between Shiites and Sunnis in Baghdad, or between Protestants and Catholics in Belfast - those show up in different parts of the world.

Religious pluralism is neither mere coexistence nor forced consensus. It is a form of proactive cooperation that affirms the identity of the constituent communities while emphasizing that the well-being of each and all depends on the health of the whole. It is the belief that the common good is best served when each community has a chance to make its unique contribution.

One of the best ways of showing pluralism in action is for people to do service together, and that has so many benefits.

The totalitarians in the world are very, very small. Only the smallest part of humanity wishes and acts upon the destruction of others. The pluralists are far larger. Those of us who believe in a world where we live together - we're far larger. The problem is we haven't made our case compelling across the world yet.

To teach your child to only be a Muslim in Muslim spaces or only a Christian in Christian spaces means in a way that you're teaching them a religious identity that is relevant to only a very small part of their lives, because the vast majority of their lives in the 21st century are going to be lived in interaction with others.
