Islamic fundamentalism comes from one source, the book that you learn from, for that teaching is the yardstick for your existence, nothing else. Like every other religion the world has known it takes and deviates the writings of the ancient Prophets to make viable that which is in reality false. As each new religion has emerged the founders and their heirs have grown fat on the greed of its adherents for a salvation they will never see built, on promises that will never be fulfilled. And each one, Islam is no exception, was fed by the cult of death. All these are religions to set people against the God of Israel who is of course the Lord Jesus Christ and for whom the prophets came in the first place starting at Genesis with God's promise of a " seed." A seed not of this world yet given in union with a virgin's egg to make Him a human worthy of being called Jesus, God with us. What has Islam and its violence got to do with that?
