Those who say "I'm a Christian" or "I'm a Muslim" have just created in their mind a way to understand reality via an archaic text. They find this an easy way of understanding the world without confronting the real world, such as science, evolution, and snakes that don't talk. They find the thoughts of a god as a daddy figure comforting and warming, rather than thinking of whether or not it is actually true. I contend there are no true Christians or Muslims, just delusional people.
