A nation needs to foster unity not just diversity

The multicultural trend was…manifested (in the USA) in a variety of legislation that followed the Civil Rights Act of the 1960s, and in the 1990s, the Clinton administration made the encouragement of diversity one its major goals. The contrast with the past is striking. The Founding Fathers saw diversity as a reality and as a problem: hence the national motto: e pluribus unum,…”The one absolutely certain way of bringing this nation to ruin, of preventing all possibility of of its continuing as a nation at all,” warned Theodore Roosevelt, “would be to permit it to become a tangle of squabbling nationalities.” In the 1990s, however, leaders of he United States have not only permitted that but assiduously promoted the diversity rather than the unity of the people they govern.
