“If you will not have God (and He is a jealous God), you should pay your respects to Hitler or Stalin.” ~ T. S. Elliot.
I believe Elliot is right—it is generally the atheists who become the foot soldiers of ideologies like fascism, nazism, and communism. God is man’s psychological need. If you don’t believe in God, you might be driven to surrender your mind to any Hitler or Stalin, or a philosophical cult. Atheism is based on the idea that people can live on reason alone—but this is not true.
People cannot use their reason until they have an identity, which comes from their ability to answer the two questions: Who am I? Where am I from? In most societies, it is religion which provides the answers to these questions. When religion becomes irrelevant, people lose their sense of identity and become an easy prey for the totalitarian atheistic movements.
