Some immigrants integrate well. Others don't. I don't see it as being religion specific.
Is running the local drug scene integrating? I guess not. Those doing so in my home town, and many others, are not Muslims.
As for protesting, there are those that don't like what's going on but don't want to get involved. By only taking notice of what's on MSN and social media, and ignoring the average person on the street, your ideas are being swayed.
I don't see every non muslim out protesting wars involving non muslims.
