I'm really not interested in seguing into a discussion of how UK deals with immigration issues.
I read somewhere recently that within a few years (if not already), Islam will be the most practiced religion in the world. Well over a billion people. If the worst of them were really indicative of all Muslims, they'd have taken over everything already. The truth is, most of them are peaceful, contributing members of society. I think there are several prominent examples who put Christians to shame for better emulating Christ.
