Islam has some of the best defenses against other god viruses and has the potential to be more parasitically aggressive when consolidating political power with a society.

The lancet fluke (Dicrocoelium) infects the brain of ants by taking control and driving them to climb to the top of a blade of grass where they can be eaten by a cow. The ingested fluke then lays eggs in the cow gut. Eventually, the eggs exit the cow, and hungry snails eat the dung (and fluke eggs). The fluke enters the snail's digestive gland and gets excreted in sticky slime full of a seething mass of flukes to be drunk by ants as a source of moisture.

Some people who experience a religious conversion seem to undergo a personality change. They can be quite congenial and easygoing when talking about mundane things, but when they start talking about their faith, their demeanor changes. Their tone of voice modifies, their smile becomes tense and they become defensive when questioned about their evidence for belief. It becomes difficult to have a friendly conversation with them.

Once infected, the individual [infected with a god virus] cannot detect major contradictions in his beliefs and behavior. Belief systems become self-evident to him, and no amount of logical discourse will move him from his belief. If a Mormon and Catholic were to debate the merits of their respective religions, neither could see his own inconsistencies and logical fallacies, but would see the other's quite clearly.

We acquire both the language and religious concepts from our immediate culture – at the same time. A child cannot discriminate between useful survival information and the emotional and psychological manipulations of religion. Once infected, these ideas are deeply embedded and almost impossible to change.

Many of them [people who escaped religion] recounted both the terror and the relief they felt after leaving religion behind. Terror at realizing there was no longer an imaginary friend; relief that no one was looking over their shoulder any more. Several described the experience as similar to that of a child learning to go to sleep without a favorite teddy bear. Others described it as simply growing up or outgrowing the need for the imaginary friends of childhood.

Religious people use 10% more pornography than secular people. The biggest consumers of pornography are Utah and Mississippi. All that religious preaching does no good.
