"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 . . . 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 . . . 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 . . . People with low intelligence (because of inbreeding) might also be easier to brainwash with fundamentalist Islam. "
My emphasis.
Sez is all about Muslim mental problems and aggression. Everything is about the clan and family and keeping wealth within it so no out-marraige
