Prejudice, immature attitudes, and unbecoming behaviour have no place in any rational society. This goes along with the fact that members make such a society what it is in the eyes of non-members. Actions which bring criticism upon the members bring criticism upon that society.
Prejudice is a partiality that prevents objective consideration of an issue. An immature attitude lacks sensitivity or intelligence in outlook. Unbecoming behaviour impairs the quality of the actor's life or that against whom such behaviour is directed.
