"Conversation is a game with some hard rules: say only what you mean; say it as accurately as you can; listen to and respect what the other says, however different or other; be willing to correct or defend your opinions if challenged by the conversation partner; be willing to argue if necessary, to confront if demanded, to endure necessary conflict, to change your mind if the evidence suggests it."

David Tracy. Plurality and Ambiguity, p. 19.

The problem with being part of an "ism" is that the last phrase of Tracy’s definition of a conversation almost never comes into play.
