These people have an inability to accept any people other than themselves. They don't like working in multicultural situations. They don't like people with accents. They don't like difference. A definition of what diversity and multiculturalism means for our university may be a good starting point towards answering the question.
Diversity is about the many groups of peoples that compose America, the plures.
It deals with the difficulties in developing a just society for all Americans, the experience of exclusion. Diversity, therefore is framed within the unique history of the American culture, rich in its ethnic roots, its continuous exposure to other cultures, and its fundamental affirmation of individual freedom. Multiculturalism can be seen as a more universal concept. In its complexity, then, multiculturalism implies the cultivation of a global view of human affairs. Multiculturalism implies a will to communicate with other cultures and to appreciate their achievements.
