Etiquette firmly opposes both obscene and malicious talk, but this does not imply that speech needs to be restricted by law. Etiquette does not necessarily even oppose the expression of offensive ideas. Rather, it dictates that there are situations in which the expression of potentially offensive, disturbing, or controversial ideas is inappropriate and that, where appropriate, the expression and discussion of such ideas is to be done in a civil manner. Which one of the following judgments most closely corresponds to the principles of etiquette stated above? ['The journalists at a news conference should not ask a politician potentially embarrassing questions about a controversial policy issue.', 'The moderator of a panel discussion of a divisive moral issue should not allow participants to engage in name-calling.', 'Neighbors should not be gruff or unfriendly to one another when they meet on the street.', 'When prosecutors elicit testimony from a cooperative witness they should do so without intensive questioning.']
