Fundamentalism in most of its forms is the active creation of antibodies to some threatening [god] virus. As long as threatening religions or mutations [heresies] are present, fundamentalism will churn out antibodies to keep the population under control and prevent mutations from getting out of hand.

Jesus must have been married to have been called a rabbi.

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.

Simply disabling specific critical thinking skills is all that is necessary for the god virus [to take control of a person].

Religion has the capacity to silence critical thinking and create blindness in entire groups of people. It can infect the minds of followers so completely as to allow the most egregious sexual acts against children and others to go unchallenged for centuries.

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.

Have you ever observed somebody go through a religious conversion? The person seems perfectly reasonable to you and has no particular concern for religion. Then a parent, friend or child dies or he gets a serious illness or is involved in a car accident. In just a matter of weeks, he seeks out and finds the answers to all of life's questions and starts studying and spouting all sorts of doctrine. During such a window of vulnerability, religion can commandeer a person's brain.
