Fundamentalism is religion after all its questions have been answered, all its passions have been quenched and all of its creativity stifled. In other words, fundamentalism is religion after it has died.
And religions do not die peaceably. They are like headless chickens running about the barnyard pecking and scrapping. Fundamentalism cannot leave others alone. It must seek out the warm blood of sinners because it has no warmth left of its own. It has lost its own living heart of love, so if it has no one to convert or criticize, it has nothing to say.
