Let's say, oh, an immigrant's religion decree's that a teenage boy should carry a killing dagger at all times, including when he attends high school classes, that being against the laws of the society he now resides in.

Should such "diversity" be accepted and "accomodated" against the values and the laws of the society?

Perhaps other people will respond in more detail to your question. However, right now my mood is much too mellow to respond in any depth to your legitimate question.
