No desperation here.  Try Napoleon Bonaparte if you like.  Napoleon was actually taller than the average Frenchman, but it's 100% fine for Wikipedia's article about him to mention and dispel the misconception about his shortness.  There are numerous myths about the holocaust.  Here are several, according to a Northwestern University historian: 

 *Anti-Semitism played a key role in bringing Adolf Hitler to power. 

 *Killing Jews was on Hitler's agenda from the beginning of his political career. 

 *The Allies could have saved more Jews 

 *Jewish resistance could have reduced the death toll. 

 *Greater popular solidarity with or sympathy for Jews in German-occupied countries could have saved large numbers of the victims. 

 *Killing the Jews diverted large German resources from the war effort. 

 *The persecution and slave labor system were driven primarily by greed 

 It's fine for Wikipedia to mention such misconceptions as long as we give the actual mainstream version too, as a corrective.  Your description of Wikipedia's policy about history articles is as accurate as the NRA's description of Hitler's gun control policy.
