Then you get the problem of people trying to culturally assimilate, but who are restricted from doing so, at all points.
Religion does have a way of preventing or slowing cultural assimilation, when the dominant culture is of a differing religion than the immigrating culture.
The only way to facilitate assimilation in that context is to make religion a non-issue. I.e., welcome all comers. (The opposite of what AB is calling for)
