Promoting tolerance is seen as a key weapon in battling prejudice in diversity and multicultural training but its meaning has been modified recently. The classical definition of tolerance meant that others are entitled to their opinions and have the right to express them and that even though one may disagree with them, one can live in peace with such differences. In recent years, however, tolerance has come to mean that all ideas and practices must be accepted and affirmed and where appreciation and valuing of differences is the ultimate virtue. Such a neo-classical definition has alienated many who value equality and justice and limits the effectiveness of diversity initiatives that teach the promotion of tolerance. The authors offer authentic tolerance as an alternative, incorporating respect and civility toward others, not necessarily approval of their beliefs and behavior. All persons are equal, but all opinions and conduct are not equal.
