I'm under the impression that Michigan has a lot of Arabs, period, they are from Egypt, Lebanon, Morocco and so on. They even have a few Christian Arabs.
Somehow, for the "Little Mogadishu", there was just a large transplanting of Somalis in Minnesota, some of that not wanted by the local populace, some of that done by Churches and I guess, the US Government. So, the vast number of Muslims in Minnesota would be from Somalia vs. the situation in Michigan and even some other states. Hence, the Somali community is rough around the edges, from one of the world's ultimate backwaters and a desert at that and definitely with a number of radical Muslims, a good number living in public housing and things like that. Apparently, there are also a number of Somalis in Nashville and other places as well.
There are Arab American newspapers, news websites that one can visit. I think one is from Dearborn and Chicago.
