Rudeness (also called effrontery) is a display of disrespect by not complying with the social norms or etiquette of a group or culture. These norms have been established as the essential boundaries of normally accepted behavior. To be unable or unwilling to align one's behavior with these norms known to the general population of what is socially acceptable is to be rude and are enforced as though they were a sort of social law, with social repercussions or rewards for violators or advocates, respectively.
Rudeness, "constituted by deviation from whatever counts as politic in a given social context, is inherently confrontational and disruptive to social equilibrium" . Rudeness, particularly with respect to speech, is necessarily confrontational at its core.
Forms of rudeness include acting inconsiderate, insensitive, deliberately offensive, impolite, a faux pas, obscenity, profanity and violating taboos such as deviancy. In some cases, an act of rudeness can go so far as to be a crime, for example, the crime of hate speech.
Both manners and morality deal with whether a thing is morally good or bad, but at different levels. Unlike morality, which, for example, condemns murder as a violation of a person, manners primarily concerns itself with violations of human dignity, rather than the person's health or property . Rude behaviour is a violation of human dignity or of the respect due to others.
The specific actions that are considered polite or rude vary dramatically by place, time, and context. Differences in social role, gender, social class, religion, and cultural identity may all affect the appropriateness of a given behaviour. Consequently, a behaviour that is considered perfectly acceptable by one group of people may be considered clearly rude by another. For example, in medieval and Renaissance Europe, it was rude to indicate that a man wearing a mask in public could be recognized . Instead, polite behaviour demanded that the masked person be treated as a completely unknown person and that no one ever attribute the masked person's actions to the individual who performed them. By contrast, in the modern era, greeting a friend by name while he is wearing a mask, or talking to them later about their costume or activities, is not generally regarded as rude.
Sometimes, people deliberately employ rude behaviours to achieve a goal. Early works in linguistic pragmatism interpreted rudeness as a defective mode of communication. However, most rudeness serves functional or instrumental purposes in communication, and skillfully choosing when and how to be rude may indicate a person's pragmatic competence.
Lakoff 1989 addressed what she named 'strategic rudeness,' a style of communication used by prosecutors and therapists to force their interlocutors (a courtroom defendant or patient) to talk or react in a certain way. Rudeness in everyday speech "is frequently instrumental, and is not merely pragmatic failure" . Most rude speakers are attempting to accomplish one of two important instrumental functions: to vent negative feelings, and/or to get power .
In every culture, it is possible to act rudely, although what constitutes rude behaviour varies. The following are examples of behaviour that many Western societies would consider rude or a breach of etiquette, though views may vary by culture, setting, or individual circumstances:
What constitutes rude speech depends on the culture, the setting, and the speaker's social position in the culture. In every culture, some words or statements are considered hate speech or inappropriate ethnic slurs (such as using the word Hun to a German, using the word Jap to a Japanese person, etc.). In most modern cultures, insulting a person or group of people, especially for any reason outside their immediate control, such as having a medical condition, following a particular religion, or being poor, is considered rude. Rude speech also includes derogatory terms describing an individual person and asking inappropriate questions or pressing for answers to a question.
However, there is no universal rule about which terms are considered derogatory and which questions are inappropriate under what circumstances. A question or comment that is acceptable between family members might be resented from strangers, just like a question that is acceptable among young people in one culture might be unacceptable to older people or to young people in a different culture.
Rude ways of speaking include inappropriately discouraging a person's participation in a conversation with rude phrases, such as shut up or using a tone of voice that indicates disrespect for the other person. An impolite tone may amplify obviously rude remarks or contradict nominally polite words. A rude person may interrupt a speaker to indicate that the first speaker is unimportant.
Failing to speak can also be rude: a rude person might pointedly ignore a legitimate and polite greeting or question to communicate disregard for the other person, or might fail to express appropriate thanks for favors or gifts by way of communicating either a sense of selfish entitlement or a disregard for the efforts of the giver. Sometimes people will leave very short gaps when speaking that may allow another person to begin speaking on a subject, however that can vary, and sometimes two or more people speaking at the same time can be considered rude. Which acts and communications require a response from which persons, under which circumstances, and what kind of response is required, depends on the culture and the social situation of the people concerned.
Many behaviours can be rude. These often depend upon the context, including time, place, and culture.
This includes a failure to dress appropriately for an occasion, whether by dressing too informally, too formally, immodestly, or otherwise inappropriately (e.g., a young woman in public without a veil in Iran; a young woman in public with a veil in France). C. S. Lewis writes that "A girl in the Pacific islands wearing hardly any clothes and a Victorian lady completely covered in clothes might both be equally 'modest,' proper, or decent, according to the standards of their own societies"--but that in each culture, the idea of immodest, improper, and indecent dress existed, and that violating the culture's standard was rude .
Rude behaviours often disturb other people, such as making noise or playing loud music. An acceptable level of sound depends on the context: yelling might be the only way to be heard at a noisy construction site, and rock concerts are expected to feature loud music, but a conversation at a normal level, either by telephone or in person, might be rude in an environment where a reasonable degree of silence is expected, such as a library, and complete silence is expected at other times, such as during religious ceremonies or performances of classical music. This includes speaking over a presentation or film with no consideration for the other viewers. Similarly, poor table manners can disturb or disgust nearby people, as can yawning, coughing, farting or sneezing without covering the mouth.
Other rude behaviours have the effect of communicating disrespect for other people. In extreme cases, this can rise to complete and deliberate social exclusion of the disrespected person; in others, the rudeness is only temporary and may be unintentional. For example, it can be rude to use electronic devices, such as mobile phones, if this results in ignoring someone or otherwise indicating that the present company is less interesting or important than the people elsewhere or the text messages they send. Similarly, cutting in line signals that the person cutting in the line believes themselves to be more important that the people their action delays. Barging into someone else's space without permission, whether that be a violation of personal space or crashing a party, is rude because it does not respect the person's property rights or right to make personal choices.
