Crime and culture, like I said. One guy I read is even speculating that Europe will be Muslim by 2100. The debate has now shifted from what is good economically, and how they can help impoverished people to whether their very culture, religion and way of life are threatened. Our immigration issues pale in comparison IMO. Crime is an issue, but Mexican immigrants bring strong families, Christian faith and a desire to work hard and earn a living. Perhaps fear and culture is a better way to put it. Sometimes the fear is justified by real crime, and other times the issue is just fear.
