It is an established fact that Muslims have twice the number of mental health problems as non-Muslims.  This is explained in part by their theological beliefs.  Their beliefs fall into two categories:

1.  What the Koran teaches (67% irrational).
2.  What Muslims claim the Koran teaches (3% irrational).

The problem is, as studies show (from RealiLty Rules), Muslims follow #1 (Koran teachings) 98% of the time and #2 (claimed Koran teachings) only 2% of the time.  In plain English, most Muslims are liars and follow an irrational theology.
