Leftist Polemics 101.
Andrew Breitbart appeared on Bill Maher's "Real Time", along with (self-)celebrated social critic Michael Eric Dyson*. The results were as one would have expected.
It was an exercise of textbook leftist polemics. To win a debate, you must control the arguement. To control the arguement, you must control the language. As when Dyson defines what Breitbart says as racist code.
Two Russians are on a train, and one asks the other, "where are you going, comrade"? "Kiev", answers the other. "Liar!" shouts the inquisitor, "You say you are going to Kiev so that I will think you are going to Moscow when you in fact are going to Kiev! So why do you lie?"
*Dyson's new book he is now hawking is called "Can You Hear Me Now?: The Inspiration, Wisdom, and Insight of Michael Eric Dyson".
