Wikipedia:WINDMILL

Don Quixote tilted at windmills. You probably shouldn't.

Sometimes when editing, it becomes apparent to an editor that there is systematically SOMETHING WRONG with an aspect of Wikipedia policy or practice. It can be very tempting to try and tackle this problem head on by doing the same repetitive edits to a series of articles or project space pages. Occasionally when undertaking this, it becomes apparent that these edits are not having any appreciable effect; your tags are being removed from articles by other editors, your articles for deletion nominations are not resulting in article deletion, or you are the lone opposer in multiple discussions. At this point it can be very tempting to continue going on and fighting the good fight, because even though several editors have asked you nicely to stop, you are Absolutely Right... it's everyone else who is wrong, and it is up to you to fight a lonely battle for the TruthTM.
