Those imported muslims living in ghettos are different than how it looks living in true muslim society in Iran before this whole ISIS/taliban mess took place. Them muslims in ghettos of large Europeans cities are of criminal type but still very modern in most aspects. True muslim society looks like something from 17th century.
As I've previously mentioned, my childhood took place in small town in central Bosnia. Before the war Yugoslavia was very multicultural, it was typical to have muslim families living next to their catholic and orthodox neighbors. Since religion was put on a leash (by communist government) there were no issues and people pretty much looked the same. You can find picture of Soviet Afghanistan and get a fairly good picture how that looked like.
Today that place looks like taliban village/fortress. Before the war there used to be mosque, catholic and orthodox church. Right now there is just a mosque in center of a town and it is main building. No clubs or any other form of entertainment. Mosque is main gathering place and they made sure people several hills away from this town can hear when muslims are having a prayer. Compared to how it was before, this place now looks like it went several centuries back in time. Truly a sight to behold.
Until you spend some time in a place like that, you won't be able to get the full picture of modern Islam. These turbo muslims who live in scary neighborhoods of European cities in are very different and a lot more aggressive. While they will willingly blow themselves up in the name of Allah, these so called moderate muslims won't act individually but whole society will gather to punish those who don't follow the word of Allah.
