Terrorism is not the sole property of Muslims. There is terrorism motivated by religion, including Islamic terrorism, but also Christian (the Ku Klux Klan, people blowing up abortion clinics in the US), Hindu (Indian Hindutva nationalists killing Muslims), Jewish (attacks by fundamentalists on Arabs in modern-day Israel), Sikh (the assassination of Indira Gandhi), and so on. Or you have non-religious terrorism such as the nationalism of Anders Behring Breivik, or eco-terrorism.<p>The reason for terrorism is extremism in all its forms, not Islam.
