Yes, I heard about that. I guess the difference between the US and Europe, is that many Muslims who immigrate to America do so for studying or they are already well educated. Instead in Germany, most immigrant Muslims came here as "gueast workers" 50 years ago and were farmers in there home country, so they didn't get the same acceptance. Now, the next (more educated) generations try to build up an other image.
Are there many parallel muslim societies in the US? Cause that is a big social problem in big cities here, which is due to the past and to poliical incompetence, as well.
