I very much disagree. Christianity was set up as a religion seperated from state governance and only began to find its way when Protestants emerged to challenge the Catholic church. Islam's base was set up to show no seperation. Looking at this from the religious point of view.....
Jesus said, "Render unto Ceaser that which is Ceaser's, and render unto God that which is God's." This clearly demonstrates a difference between a heavenly plain and an earthly plain. Muhammed was a General and a soveriegn. Therefore he was his own Ceaser. Both inventors had entirely different prescriptions for their religions. Would Christianity look different today had Jesus been a General or a soveriegn? Would Islam be different had Muhammed been a simple carpenter and a hippie? There is a sense of superiority and demand for power that cultures assume when their religious icons ruled empires....and it ripples down through history. For Catholics....it was the "victimhood" of Jesus on the cross. For Muslims, it has been about the glory of Muhammed. After all, in the end, Muhammed died successful and empowered. Jesus was executed.
Of course, Christianity would lose its path rather quickly. And Islam did the same upon Muhammed's death with the Sunni insisting on a vote for succession (resembling a sort of democracy) and the Shia insisting on a devine blood line (resembling a monarchy).
Over the course of history, the Sunni would lose stewardship of Islam to the converted Turks. And it was at this time, the Sunni elders put the breaks on Islamic progression insisting that the Ottoman Caliphate kill the mobile printing press, which was in Turkey, the only observatory, which was located in Istanbul, and insisting on an abandonment of social progress. Whether because of a sense of lost pride having lost Islam to outsiders or just an attempt to turn back the clock to Islam's "Golden Age" when the Sunni laid the law, all of these type things encouraged the idea that Islam was government.
I don't think Islam is as poised to assume a seperation from state as Christinaity was. This is not to say it is impossible, but people need to recognize that democracy from one culture to the next will not be the same and that many will stamp their own brand of democracy upon the earth. But I am a firm believer that the roots of the religions are more important to understanding today's crisis' than people think.
