immigrants are expected to come to a new culture/country and EMBRACE the beliefs and laws as far as freedoms and government. Not necessarily adopt a flavor in music or a religious opinion.
The problem is when someone immigrates to, say, America and they try to enforce their own beliefs that differ from the American Constitution or local laws. I.e. an extremist from the Middle East who comes to America and is unwilling to accept the fact that here women are allowed to show their faces and have RIGHTS and that husbands can't just beat their wives because of some sort of backwards ancient custom
