Thirty years ago, many Europeans saw multiculturalism—the embrace of an inclusive, diverse society—as an answer to Europe’s social problems. Today, a growing number consider it to be a cause of them. That perception has led some mainstream politicians, including British Prime Minister David Cameron and German Chancellor Angela Merkel, to publicly denounce multiculturalism and speak out against its dangers. ...

Multiculturalism and assimilationism are different policy responses to the same problem: the fracturing of society. And yet both have had the effect of making things worse. It’s time, then, to move beyond the increasingly sterile debate between the two approaches. And that requires making three kinds 
of distinctions.

First, Europe should separate diversity as a lived experience from multiculturalism as a political process. The experience of living in a society made diverse by mass immigration should be welcomed. Attempts to institutionalize such diversity through the formal recognition of cultural differences should be resisted.

Second, Europe should distinguish colorblindness from blindness to racism. The assimilationist resolve to treat everyone equally as citizens, rather than as bearers of specific racial or cultural histories, is valuable. But that does not mean that the state should ignore discrimination against particular groups. Citizenship has no meaning if different classes of citizens are treated differently, whether because of multicultural policies or because of racism.

Finally, Europe should differentiate between peoples and values. Multiculturalists argue that societal diversity erodes the possibility of common values. Similarly, assimilationists suggest that such values are possible only within a more culturally—and, for some, ethnically—homogeneous society. Both regard minority communities as homogeneous wholes, attached to a particular set of cultural traits, faiths, beliefs, and values, rather than as constituent parts of a modern democracy.
