"Allaah suffered from ambivalence..."

Here is part of the testimony of Abd al Quddus, a former Muslim. His tone is polemic to be sure, but his entire story is certainly worth a read. He explains his experience very well I think and sheds light on the work of Islamic da9wa (proseltyzing) in the West. From Here:

My expectations of a Supreme Being [were] in contrast to the conventional god of Prophet Muhammad. I yearned for a deity that was transcendent, incomparable, and an indefinable holy unable to be conceptualized. To my discovery, the Islaamic deity was actually the generic anthropomorphic Sky Father abound in popular mythology. He was afflicted with psychological infirmities such as megalomania, melancholy, and malevolence. Allaah suffered from ambivalence, claiming to be ar-Rahmaan, ar-Raheem (The Most Merciful, The Most Beneficent), while simultaneously being malicious or fastidious. As an omniscient entity, he should have exhibited irrevocable authorship in his scripture, instead of acting capricious by amending and abrogating revelations like a fallible redactor confused about what He should have written initially. On the one hand, there is the incapacity of man to grasp the nature of omnipotent Allaah, yet His Will can be altered by exterior forces such as the affects of human prayers. I could not worship a God that changed. As just another idol, Allaah was depicted and contained in the literary work of al-Qur’aan. According to one hadeeth (Sahih Bukhari: Volume 8, Book 74, Number 246), the Islaamic God created Aadam upon His soorah (form, shape, image), sixty cubits in height. Allaah rested upon His Throne (arsh) near His Footstool (kursi). He claimed to have an Eye (20:39), a Shin (68:42), a Face (55:27), a Foot (Sahih Bukhari: Volume 9, Book 93, Number 541), even both Right and Left Hands (39:67). Surely, there were many “comparable unto Him.” (112:4) Discovering Allaah to be as mythical as the elephant-god Ganesha or temper tantrum Yahweh was a devastating blow to my heart. Relying on tawheed, the initial attraction to Islaam, was ineffectual for I now discerned Allaah as fictitious like the rest of the idols. The god of Islaam, likely just Muhammad’s alter-ego, displayed masculinity, anger, indecision, misogyny, and other moral weaknesses unbefitting of a majestic deity. Between Muhammad and Allaah, there was an uncanny resemblance in personality. Similar to the 1939 musical fantasy film, ‘The Wizard of Oz’, I realized that the Wizard (Allaah) was a fabrication concocted by the man (Muhammad) behind the curtain.
