@jetsam,
In my opinion, they have to integrate.. But there is a problem, they never had to integrate.. They were born and raised up in there homecountry.. So it will become an issue if they can't or don't want to integrate..
I'm a muslim, but I'm a foreigner in a country where I'm now living in.. I'm born and raised up here so not really a big issue.. But again, even integrating here was hard for me and even more for my parents (doh).
- I shake hans with women;
- I even don't pray (I'm sorry), sometimes on fridays when I don't have to go to school or work;
- Halal food, that will become an issue.. They have to bring their own meals I think or not??
