Yes, mixing governance and Islam has always been a carnal idea. This worldly approach to Islam has always led to numerous forms of sin and degenerations. As we see in the history of Bani-Umaya and Bani-Abbas, huge group of Muslims left Islam and became heretics or joined other religions. Today if the pressures and suppression of religious despotism were removed from this country, you will see that the result of combining religion and politics has been nothing, but depriving all the people of monotheism and spirituality.
