Personally, I think it's more related to that many immigrants have a hard time to understand the highly individualist society when coming from clan societies, the case that many of them have traditional and backwards values that is frowned upon in the rest of the society although it's never ever done in the open, the islamists and wahhabist propaganda that uses them for their own purposes, and even how we put them in areas where the brutalist architecture, disappointing, misguided, and dirt-cheap city planning amplifies the social group dynamic effects that could perhaps been kept in check in a more non-anonymous society (as explored by Philip Zimbardo.)

And class ( or socioeconomic background - there are related problems that are ignored ). And education. And the fact that we have not done anything to prevent this for the past 30 years.
