“Government role”?–sure. Public schools should focus on English, not the immigrants’ language of choice, right? A preference for traditional American cuisine in school cafeterias–why not? That’s not to say you can’t have tacos once in a while, or egg rolls now and then–but not every day. And local governments have to decide which sports to build fields for, or else not build them at all (the libertarian solution, I suppose). I’m not talking about prohibiting cricket or Spanish or kung pao chicken, but I do think that the government has a role to play in encouraging immigrants to embrace many elements of American culture, and NOT encouraging them to NOT to assimilate.
