Wikipedia:WikiCrusader

A 'WikiCrusaders' is a wikiuser who wage an all out assault on certain articles or topics to push their point of view over the top until the whole online world is forced to accept it as truth. Curiously, they don't believe they have any sort of POV, but everyone else does, and needs to be clearly tagged as such. They recognize Wikipedia as humanity's last battleground for fighting for the truth of such forgotten concepts as astrology, communism, or theism. If they can win here, they can win anywhere.
