Back in the 60s-70s, when the "Guest workers" were recruited, almost everybody expected them to go home after a few years, actually many from Portugal, Italy and Spain have done exactly this, they saved their money and went back to their countries of origin to e.g. buy some land or start a business (I´ve met quite a few Spanish in their 40s-50s on my travels, who told my that theyhave spent some time in Germany). Many Turkish though, completely legal, used another option, meaning to stay and live permanently in Germany.
Now, the problem in Germany is that most Germans and many of their political class have and are still denying that Germany turned into a country of immigration. The political right, because they are afraid that it might attract more immigration and out of racist reasons and the political left, because they lived in a fantasy of tolerant multi culturalism where everything would turn out nicely if left alone.
As a result Germany never had any immigration legislation, regulating the necessary immigration within acceptable limits, but on the other had so many loopholes where, not always desirable persons could slip through, notably our political asylum laws. Based on the experiences of the Nazi regime, the constitution guarantees political asylum, but it can be very easily used by fake asylum seekers (I know, because I´ve been married to one for 6 years), mostly uneducated people with a certain streetwiseness and not very scrupelous when it comes to milking the social welfare system.On the other hand, real refugees and qualified specialists and other hard working people are not being admitted in Germany out of political reasons (high unemployment, but e.g. with a shortage of nurses, does somebody seriously expect an unemployed German builder of 50 years to be retrained as a nurse just to be able to employ a German?). A foreign nurse from a non-EU country and a handfull of other countries can at the moment, even if she has the right professional credentials and speaks German only live and work in Germany if she marries a German citizen or a permanent resident.
A few years ago, the Schroeder government tried to pass an immigration bill based on Canadian immigration laws to control immigration, based on a point system concerning background, education, family etc., but it was voted down by the at this time conservative majority in the Bundesrat (equivalent to the American senate).
One result of this lack of immgration gegulations was that for 30+ years almost nothing has been done to actively integrate the defacto immigrants into our society (one basic item for me would be a proof of reasonable German language knowledge for a permanent work/residence permit), because everybody figured that they would go back to their countries of origin some day.
Back to the topic, the first 70 odd articles in the German constitution spell out the basic rights and duties of any person residing in Germany. They include religious freedom, right of free speech and it´s limits, equality independent of race, origin, religion and sex.
An immigrant HAS to abide by these rules, he can´t just pick whatever he likes. If he complains about hate speech e.g. by Neo-Nazis against immigrants, then he can´t complain if his own hate propaganda against the local population gets censured. These laws are equaly valid, both for immgrants and the local population.
If the immigrant doesn´t like the laws here, well, there is the door, don´t let it hit you on your way out!
BTW, concerning the religious fascist, in my opinion they have to be fought and persecuted just like Neo-Nazis and Stalinists, before they can do damage.
The idea of the radicals is that, because they follow "pure" Islam, God should make them rule the world.
