Supposed Crimes of the Mind - Victor Davis Hanson

Victor Davis Hanson shows that , "With hate speech, it’s the perceived ideology of the perpetrator that matters most."  Read his article on NationalReviewonline.com 

Apparently, racist, sexist, or homophobic words themselves do not necessarily earn any rebuke. Nor is the race or gender of the speaker always a clue to the degree of outrage that follows.

Instead, the perceived ideology of the perpetrator is what matters most. Maher and Letterman, being good liberals, could hardly be crude sexists. But when the conservative Limbaugh uses similar terms, it must be a window into his dark heart.

 So basically, he says that with PC speech, that Libs are hypocrites.  Think Babs Boxer, Bob Packwood, and Bob Fillner.  With the former, a republican, he must resign due to the seriousness of the accusation; with the later, eyewitness testimony is not enough to demand resignation.
