"The United Nations says there is a significant rise in religious extremism and intolerance throughout the world. 'No religion is free from extremism,' declares Abdelfattah Amor, the UN's Special Rapporteur on Religious Intolerance." http://allafrica.com/stories/19991220004.html .
I have had firsthand experience with extremism in my family. My father was brought up in a fundamentalist Muslim home. He was an Islamic extremist. Later he became a Christian, through meeting loving Christian missionaries. He was thrown out of his hometown and disowned by his family. My sister and I were born into this Christian home.
I had come to expect that I would probably never see my father's family, and without realizing it, I had in my own way disowned them. I was sure our Christian way of living and worshiping was the only correct way.
