Diversity and Equality are words that are used to mean a bewildering array of things.  Diversity and Equality had gone beyond the scope of mere definitions of words in 1990.  Diversity and equality are now words that can only be defined by people.  Most people now have different views of the definitions of diversity and equality based on their political beliefs..

DEFINE DIVERSITY – MANAGE DIVERSITY - DEFINE EQUALITY - MANAGE EQUALITY
"Managing Equality and Diversity: Theory and Practice"
Managing Equality and Diversity: Theory and Practice offers a unique learning experience and an innovative approach to an increasingly important subject area, and offers students a solid foundation in equality and diversity management, while fostering a strong understanding of its practical application in business.  Many people see “diversity” as a goal in itself.  Those who disagree can be labelled as racists, sexists and other vile things. Many see “equality” as being purity.  These egalitarian people will not accept theories suggesting some people may just be worth more because they can do more.
Taking a business, rather than sociological approach to the subject, the text supplements the theory behind managing equality and diversity with real-world practical examples, providing an insight into the contemporary issues facing today's businesses and organizations. This up-to-date coverage is combined with an accessible and student-friendly writing style, which ensures an engaging discussion of key themes and concepts relevant to equality management.

DIVERSITY is the condition of having or being composed of differing elements : variety especially : the inclusion of different types of people (such as people of different views, backgrounds, races or cultures) in a group or organizations.  In the 21st century liberal and progressive people chose to ignore the diversity of opinions not their own.
