Been saying this for years. This is the root of the problem with political correctness:

If you say, "Chairman Mao? Wasn't he the wacko who offed 70 million Chinks?", you'll be hounded from public life for saying the word "Chinks". But, if you commend the murderer of those 70 million as a role model in almost any schoolroom in the country from kindergarten to the Ivy League, it's so entirely routine that only a crazy like Glenn Beck would be boorish enough to point it out.
