I dont know why that is Sofia but I am going to speculate that it is somewhat anthropological in origin.
That religion (Islam) had been around a long time and is a survivor so it has something that makes it so.
I would venture to guess that any religion that survives grows and makes people appear to thrive is meeting a need of some type.
While Islam is not progressive of women, it is protective of them (according to its own standard) and is also set up to give very clear guides as to the family structure being important. They have in place an arrangement for financially helping their poor and other social structures that are "built in". Their are holidays with meaning, foods with meaning etc.
When you separate out being Arabic (which is different) or radical like ISSIs (Americans have a hard time with that one sometimes) and look at the religion versus the nationality, its clear that not all the ideas are bad. Nor even most of them.
Like Judaism, it is a culture, a religion, an identity. There is comfort and meaning in that.
Contrast that with the JWs - a new religion...they are frantically trying to instill a "culture" using the tool of uniformity. They are trying to bring in some kind of pride and fun (using technology here recently- a distinctly young American concept) and of course they are having extremely limited success. This is true not just when you compare them to stable religions rich in tradition like Islam but even when you compare them to religions of their own ilk like 7th Day Adventists or Mormons.
