There are cults within Islam. Look to the Caucasus if you want to see more or less modernized Islam. The Caucasus is that group of countries whose names no one can pronounce that sit below western Russia.
That's only Azerbaijan, that is "moderate", the rest are as faithful as Arabians. But I think the most nutter Muslims are found in Egypt (over half Muslim population upholds Islamic theocratic law for everyone (nonMuslims in, too), and it's one of the highest upholding bases for killing folk that convert from Islaam.
Middle Asia+Turkey+Azerbaijan are the hubs for "moderate" Islaam - most folk there believe in evolution, don't think that the law should follow Islaamic codes, believe in freedom of faith (they don't punish you for converting), and so on. These countries have had a long past of secularism.
