You've got problems in Central Asia. And you've got problems within our own communities back home. So if we end up saying, look, this has nothing to do with Islam or it's got no connection with that broader question, then we look, frankly, as if we're in denial about the problem.

At the heart of my politics has always been the value of community, the belief that we are not merely individuals struggling in isolation from each other, but members of a community who depend on each other, who benefit from each other's help, who owe obligations to each other. From that everything stems: solidarity, social justice, equality, freedom.
