Religion was the compelling moral force that propelledplanes into buildings on September 11, 2001. To understand why the carnage tookplace, some level of understanding of this moral force is essential. For thosewho are religious, and who do not support the overwhelming use of violence, thismoral force can be written off as a mutant strain of religion, blatantly wrong,and quite different from their own understanding. For those who are skeptical ofreligion, or hostile to it, this moral force can be viewed as yet anotherindicator of the irrational and perhaps dangerous basis of religion, not tospeak of its capacity to rouse people to commit atrocious acts with the moralinsulation of alleged divine justification. For instance, Richard Dawkinsopined, "To fill a world with religion, or religions of the Abrahamic kind,is like littering the streets with loaded guns."
