A trenchant excerpt:

As close to self-parody as they come, these speeches make clear what motivates those Americans, on campus and off, who remain in a state of moral denial even after getting a Technicolor view of evil: multiculturalism. This ideology goes way beyond preaching the tolerance that is a bedrock virtue of a pluralistic society to insisting that all cultures are equally good--regardless of whether they beat their women, practice slavery or torture political dissidents.

In earlier generations, the schools, the workplace, the entire society, pushed immigrants toward assimilating into the great American "melting pot." But as multiculturalism took hold, to require immigrant children to learn English, or be taught about the specialness of American history and the greatness of the ideas of the Founding Fathers, or to pledge allegiance to the flag, came to seem a sign of gross cultural insensitivity, even of racism.

It's a long piece, but well worth the read, particularly for parents with children in college. In fact, in rereading it, I find it impossible for me to recommend it enough.
