"Extreme religious fundamentalism, like oppressive ethnic nationalism, is not an indication of strong faith or shining conviction. On the contrary, the human being of deep, abiding faith can afford to be tolerant in thought and deed, to question and to be questioned. Those who are comfortable with their deity are comfortable with their neighbors. They are also open to change, once they are convinced of its utility. Doctrinally rigid fundamentalism is always a symptom of insecure faith. This age of resurgent belief is really one of explosive doubt. Those who feel compelled to force their vision of God on others are trying to convince themselves, thus their ferocity. The possibility that alternative paths to salvation exists, isn't an affront to their God, but a personal threat to them."
