Neither do Russians, Slavic people, Southern Europeans (per Northern European standards). Or you think Greeks or Lithuanians take the same religious care of their little front yards, cars and house as Austrians or Dutch or Germans? My point is that one can always find differentiating factors across religions and cultural groups. Where exactly do you delineate what is acceptable and unacceptable integration and adoption?
There are minor differences between other European cultures, not even comparable to differences with Middle Eastern cultures. Over there, religion dictates the law, religion in fact is indistinguishable from law. That's not a think in the West.
Then there's wearing a veil in Europe which is clearly unacceptable and even more so, forcing women to cover themselves.
One interesting case is Denmark. Denmark's second largest foreign-lineage group are the Polish but you don't hear any problems with Polish in Denmark, it's all Syrians, Iraqis, Afghans, Turks - according to the Muslims, west has to accept their ways in each way ("because you must be tolerant!") but they accept nothing different and refuse to assimilate.
People from say Lithuania, Poland, Germany or Estonia have differences but are so minor in comparison that you wouldn't even recognize them unless you inspected each group in fine detail for a long period.
