Actually, no. I live in the San Francisco Bay Area and know many assimilated Muslims (those I know tend to be black Muslims from Africa). One was my daughters soccer coach. From those I have met, I find that the educated Muslims tend to assimilate well. But I am also aware of the "communities" that some establish where they close themselves off to outside influences. So as a generalization, I would say that more recent Muslim immigrants with limited education and limited economic means have not assimilated well. Now some on your list actually were well educated, so we have a more widespread problem. Don't get me wrong, other groups don't assimilate well either. For example, poor Mexican illegals tend to stick to their own communities, with many never learning English. But boy do they learn about WIC and other social handouts quickly. In that regard they assimilate well. Assimilation is a big problem with our society. I am actually for a more widespread halt to immigration (including Europeans and Asians regardless of religion) until we can assimilate those who are already here. But for the time being, I'll take the pause and better vetting from terrorist hotbeds.
