Michigan is about 1% Muslim. 1%. This isn't Paris, Malmo, or Rotterdam. This writer equates Middle Easterner with Arab (not necessarily true) and with Muslim (even less true), and that's her mistake.
Hamtramck is probably now the Muslim capital of Michigan. Mostly Albanian and Pakistani/Bangledeshi along with some blacks (mostly Protestant). A large number of the Poles have emptied out. It's got about 22,000 people left.
Dearborn, a mid-size city of under 100,000, is still majority white ethnic. Polish/Italian/Irish. It is about 1/3 to 40% Middle Eastern, and that includes Middle Eastern Christians which are by far the majority in Michigan.
