BINGO! The same, tired old screed. Hey, the left says, you can't attack free speech, so shut up! Apparently, most of the left thinks free speech means leftist propoganda, free of criticism.
This Orwellian interpretation of free speech is the absolute essense of totalitarian activism. The idea that leftists are immune to criticism is bizarre but 40 years of media indoctrination have ensured that it reaches every nook and cranny of American society. It is the default response to criticism for all leftists, implying that their rights are somehow violated when someone disagrees with them. We heard it from the Dixie Chicks, we hear it from rank-and-file liberals on person in the street interviews. Millions are intimidated by it, because they do not know what their own rights are.
Unless you say something they don't like, then it's "hate speech."
