Actually, most problems with immigrants come from the first generation born in America. It isn't specific to Muslims. The second generation doesn't know how shitty wherever their parents were which led them to the US. They just see how their parents are treated and how their group is portrayed and they think it is unfair or whatever.
Gee golly, you make it sound like the problem has at least something to do with racism. On more than one level. Without any self-consciousness about it.
