Wikipedia:Wikiheresy

Wikiheresy (for the lack of a better word; somewhat analogous to "heresy" - being wrong about something important and refusing to change one's mind) happens when an editor of Wikipedia ("wikiheretic") strongly and persistently holds views that are incompatible with Wikipedia's nature and internal order, and acts upon them. For example, an editor who completely rejects Wikipedia:Neutral point of view or Wikipedia:No original research.

The presence of wikiheretics in Wikipedia's community is not useful to Wikipedia, nor to its community, nor to wikiheretic. Normally the wikiheretic soon understands that and either adapts to Wikipedia (for example, by softening the views in question or changing them) or leaves it. If that doesn't happen, it might be necessary to encourage the wikiheretic to leave or, in extreme cases, to resort to blocks and bans.
