Gary Schmitt and Peter Skerry note the indifference of Muslim American groups to vicious acts committed in the name of Islam. 

While Muslim-American leaders are constantly reminding their followers to exercise their rights as Americans, they also embrace the view that Muslims here are part of the worldwide community of fellow believers-the ummah. As such, these organizations are riven by numberless fissures that run along linguistic, ethnic, racial, and doctrinal lines. Their leaders are preoccupied with not saying or doing anything that would cause such fissures to develop into major ruptures.

Immigrants are obliged to acknowledge the truths of the Declaration of Independence.  Many could already teach the native-born such lessons by their example.  All need to keep in mind that being American is about duties to each other as well as rights.
