The massive inbreeding in Muslim culture may well have done virtually irreversible damage to the Muslim gene pool, including extensive damage to its intelligence, sanity, and health.
According to Sennels, close to half of all Muslims in the world are inbred. In Pakistan, the numbers approach 70%. Even in England, more than half of Pakistani immigrants are married to their first cousins, and in Denmark the number of inbred Pakistani immigrants is around 40%.
The numbers are equally devastating in other important Muslim countries: 67% in Saudi Arabia, 64% in Jordan and Kuwait, 63% in Sudan, 60% in Iraq, and 54% in the United Arab Emirates and Qatar.
According to the BBC, this Pakistani, Muslim-inspired inbreeding is thought to explain the probability that a British Pakistani family is more than 13 times as likely to have children with recessive genetic disorders. While Pakistanis are responsible for three percent of the births in the UK, they account for 33% of children with genetic birth defects.
