The fastest growing religion on the planet today is Christianity. There is a reason for that. Christianity is a flexible doctrine whose enduring truths adapt to different centuries. Christ's message is eternal.
Islam, otoh, is still stuck in the Ninth Century, which is why it is undergoing a crisis of being. As long as the Islamic world was sealed away from the rest of the planet, things were relatively peaceful. Now, Islam is confronted by modernity and the rise of Buddhist and Hindu Asia. They are not adapting well.
As for Christians, we are a relatively peaceful people. When aroused, however, Christianity takes to the sword like a duck to water.
