The Four principles of pluralism - Rabbi Irving Greenberg, CLAL 1. Pluralism is the will of G-d and any suppression of opinion is experienced as disrespect. Recognition and respect make us more competent, not less.
Pluralism does have limits.
Ultimately, pluralism will include more viewpoints than it excludes. When people engage in dialogue, two forms of communication are taking place. One is the overt transmission of information, the other is the recognition that you accord one another by the very act of communicating. Listening to someone, even when you disagree with him, affirms his value, equality and uniqueness as a person. Know your limitations.
