People tend to hold hard to their convictions on religion when they feel challenged. It's an automatic response because it feels like a challenge to their self identity. It's important to recognize that faith should not be confused with self identity. It's more like there are other religions out there and I happen to know this religion better so I follow it. It's difficult lesson to teach to most any followers of any religion but worst in the case of Islam because. 1. The amount of security Islam guarantees inside its fold 2. The scare Islam spreads outside if one tries to step out or promote the non Islamic world. It's best described by the term chakravuha - by the way I do not wish to use this term to promote Hindu viewpoints. Hindu fanatics - go hang - along with your Muslim/Christian/Sikh/Jewish counterparts.
