Many fundamentalist Muslim groups also employ a sharply dualist ideology in which everyone is either part of the group or against it. This affects how they interact with other groups, including other Muslim traditions, Buddhism,Judaism, Hinduism, Christianity, and the secular West. We know that the threat to world peace and security is not Islam, but extremism: intolerant, violent and militant extremism. The actions of these militants are beyond conscience and belief. They violate the teachings of Islam, the example set by the Prophet Muhammad, and the principles of religion.
