I have a feeling that religion, especially Christianity, will act like a scared wild animal backed into a corner. It will attack viciously when its existence is threatened. Since the rise of science and reason, religion has had some declining numbers but the amout of people that take it to an extreme level has risen. Also, there are too many people that abuse the power of religion and use it as a control method that it will be here for a very long time. It is a very useful tool to get what you want. As long as people fear the unknown elements of life, such as death, religion will be here to stay.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
