 | This is an essay on the civility policy. It contains the advice or opinions of one or more Wikipedia contributors. This page is not an encyclopedia article, nor is it one of Wikipedia's policies or guidelines, as it has not been thoroughly vetted by the community. Some essays represent widespread norms; others only represent minority viewpoints. |
 | This page in a nutshell: Responding to incivility with genuine encouragement and guidance can yield productive and meaningful results. |
The best way to approach someone on Wikipedia in regards to civility and their recent behavior (assuming that they've been responding and commenting uncivilly) is to do so in a peaceful and encouraging manner, and with words that the editor will interpret as being an attempt to provide them a friendly and informal warning about their behavior, and an offer to help them out if they need it.
