Mike Munger links to a New York Times article on the Dutch response to Muslim immigrants and rightly calls it interesting but grim reading. Read that article first. There are two parallel points I would make to responses in the United States to immigrants from Latin America.
First, crime is very low among first generation Latino immigrants (even undocumented) but it can grow with subsequent generations, particularly if people feel marginalized. There is no easy answer to this, but current state laws that essentially transform Latinos into targets for police will backfire.
Second, there was a very poignant quote that relates directly to efforts in the United States to deny citizenship to people born in the country to undocumented parents:
In the United States, citizenship once granted is never questioned, said Mr. Overbeek of VU University. “But in Europe it’s never quite established, no matter how long you’ve been here. Here it’s still, ‘When did you get here, and when are you going back?’ ”
East of Amsterdam, in Almere, the youngest city in the Netherlands, 30 percent voted for Mr. Wilders.
Shopping in the city center, Raihsa Sahinoer, 24, born here of Surinamese immigrants, was not surprised. “Wilders says we all have to go back even if we were born here,” she said. “It’s not only about Muslims, it’s about colored people, too.”
She lives as the Dutch do, she said. “But they tell us if you’re colored, you’re not Dutch.” Does she feel Dutch? “No,” she said, then paused, then asked: “What is Dutch?”
Denying citizenship (or looking at Latino citizens warily simply because of how they look or talk) will certainly make things worse. The more you pass laws to marginalize people, the more resentful they will become. And as more marginalized people become resentful, there is greater opening for neo-fascist ideas to popularize (and perhaps take violent form).
