Incivility consists of personal attacks, rudeness, and aggressive behaviours that disrupt the project and lead to unproductive stress and conflict. Editors are human, capable of mistakes, so a few, minor incidents of incivility are not in themselves a major concern. A behavioral pattern of incivility is disruptive and unacceptable, and may result in blocks if it rises to the level of harassment or egregious personal attacks. A single act of incivility can also cross the line if it is severe enough: for instance, extreme verbal abuse or profanity directed at another contributor, or a threat against another person can all result in blocks without consideration of a pattern. In general, be understanding and non-retaliatory in dealing with incivility. If others are uncivil, be understanding (people do say things when they get upset) rather than judgemental, and do not respond in kind. If necessary, point out gently that you think the comment might be considered uncivil, and make it clear that you want to move on and focus on the content issue. Bear in mind that the editor may not have considered it uncivil - Wikipedia is edited by people from many different backgrounds, and standards vary. Consider too the option of ignoring isolated examples of incivility, and simply moving forward with the content issue. Only take things to dispute resolution (see below) if there is an ongoing problem you can't resolve. This policy is not a weapon to use against other contributors. To insist that an editor be sanctioned for an isolated, minor offense, or to treat constructive criticism as an attack, is itself potentially disruptive, and may result in warnings or even blocks if repeated.
