"As Americans have left organized religion, they haven't stopped viewing politics as a struggle between 'us' and 'them.' Many have come to define us and them in even more primal and irreconcilable ways."

This attitude seems at least as evident - many would say far more evident - among the majority of the pewsitters in evangelical, fundamentalist, and conservative RC regular church attendees than among the unchurched or those still hanging in there in mainline Protestantism and progressive Catholicism.
