Here is your clue as to why Islamic peoples tend to act so completely deranged ... The systemic interbreeding, via first cousin marriages:
The Reproductive Health Journal reports the following rates on consanguinity in Muslim countries. Where a statistical range has been recorded, I have used the lower parameter:
http://www.reproductive-health-journal.com/content/6/1/17/table/T1
Algeria: 22.6%
Bahrain: 39.4%
Egypt (North): 20.9%
Egypt (Nubia-South): 60.5%
Iraq: 47.0%
Jordan: 28.5%
Kuwait: 22.5%
Lebanon: 12.8%
Libya: 48.4%
Mauritania: 47.2%
Morocco: 19.9%
Oman: 56.3%
Palestine: 17.5%
Qatar: 54.0%
Saudi Arabia: 42.1%
Sudan: 44.2%
Syria: 30.3%
Tunisia: 20.1%
United Arab Emirates: 40.0%
Yemen: 40.0%
According to the BBC, 55% of Pakistani-Britons are married to a first cousin, and as a corollary to that produce “just under a third” of all children in the UK with genetic illnesses, despite being only 3% of the total births.
As a direct result of inbreeding, the Muslim population is the only population on earth that is mentally and physically devolving. This inherent weakness makes Muslim populations more susceptible to nefarious, oppressive leadership and mass manipulation.

If you want your Islam, you can keep your Islam. Period.
