Yes what Dr Sen says about the different & many identities of a person is very true. But ther is one major difference between a religious identirty of a person & other social identities. All other social identities are the result of circumstances; ones profession , ones birth place , ones language etc... these identities are common with all the people living around & these identities are harmless ; rather these identities allow a common platform for people to be together & these identities are not the result of any crisis. But the formation religion as a social phenomenon itself is a result of identity crisis; thats why we see lot of symbols on display differntiating the religion of person from anather person. Religion is a solution to mass identity crisis & due to that it gets threatened easily by another religion which serves the same purpose for different people. And when this threat is felt by a group of people irrespevtive of any religion , it is percieved as a threat to there identity which takes an ugly turn of riot and a human being suffers.
