The Danish psychologist Nicolai Sennels has written previously about the effects of Muslim inbreeding. In the essay below he traces the possible connection between the genetic damage done by inbreeding and terroristic behavior.


The connection between Muslim inbreeding and terrorism

by Nicolai Sennels

If there are two things that characterize Islamic culture, they are terrorism and inbreeding. The latest research shows that these two things might be closely connected.

The concept of Islamic terror does not need any introduction. Not everyone might know, however, that seventy percent of Pakistanis and forty percent of Turks are inbred (Jyllands-Posten, 27/2 2009 “More stillbirths among immigrants”). Research shows that the same goes for close to half of all Arabs (Reproductive Health Journal, 2009 “Consanguinity and reproductive health among Arabs”).

First cousin marriages have been the tradition in many Muslim families for innumerable generations. Such marriages increase the risk of negative mental and physical consequences. My article “Muslim inbreeding: Impacts on intelligence, sanity, health and society” details extensive research data on the subject. In brief, inbreeding through consanguineous marriages increases the risk of depression (Indian Journal of Psychiatry, 2009 “Relationship between consanguinity and depression in a south Indian population”) and schizophrenia (American Psychiatric Press, 1982 “The role of genetic factors in the etiology of the schizophrenic disorders”).

The risk of serious illnesses or handicaps increases by up to 1800 percent (BMJ, 1994 “Infant death and consanguineous marriage”). Risk of mental retardation increases with 400 percent (Proceedings of the National Academy of Science, 1978 “Effect of inbreeding on IQ and mental retardation”). Research shows that the IQ is 10-16 points lower in children born from blood related parents and that abilities related to social behavior and empathy develops slower in inbred babies (Indian National Science Academy, 1983 “Consanguinity Effects on Intelligence Quotient and Neonatal Behaviours of nsari Muslim Children” [pdf]). Such facts might make several pieces fall into place for many people.

Here comes another eye opener:

Research published in The Journal of Aggression and Violent Behaviour has proven a connection between suicide bombers and depression and physical handicaps (BT, December 15th 2010 “Why most terrorists are useless”). Research suggests that many suicide bombers are suffering from depression, and their actions are just a socially accepted (among Muslims) way of committing suicide in order to end their mental torment.

Yusuf Yadgari of the Medical University of Kabul has autopsied the remains of suicide bombers and his findings support this theory. Yadgari found that close to ninety percent were suffering from severe illness such as blindness, cancer, missing limbs or leprosy. Many Muslim societies, including that of Afghanistan, have a low social acceptance of handicaps and severe illnesses. According to Yadgari, being physically handicapped or mentally retarded often leads to exclusion in a society like Afghanistan, and becoming a martyr might be the only chance of achieving social recognition and honour — if not just a way to end the pain of being socially isolated (which is especially traumatizing in collectivist cultures like Islam). Al Qaida’s use of people with Down’s syndrome might be another unpleasant side effect of the many chromosomal illnesses resulting from inbreeding between first cousins. People with low intelligence (because of inbreeding) might also be easier to brainwash with fundamentalist Islam.

Surely the Quran’s numerous verses ordering Muslims to fight to the death in order to spread sharia and defend the honour of their religion and prophet is the most obvious and strongest motivator for Islamic terrorism. Being an outcast due to a physical handicap, living in a country that does not manage to take care of handicapped people, suffering from physical pain following disease, or being depressed or schizophrenic, has now proved to be an important factor as well.

The unhealthy culture of inbreeding in Muslim societies increases the number of Muslim martyrs who are looking for an honourable and socially and religiously accepted way out of here.
