Glenn Greenwald has responded via his regular Salon feature (8/6/09, ad-viewing required) to Rush Limbaugh, "speaking to his audience of 15 million, compar[ing] Barack Obama to Adolph Hitler and Nancy Pelosi to Nazi leaders," by asking you to instead
compare (a) the way that a single anonymous person's comparison of Bush and Hitler swamped our political discourse and forever altered the image of MoveOn with (b) what the (non)-reaction will be to the identical comparison coming from the leader of the Republican Party who spouts his hate-mongering to an audience of 15 million people. Within that comparison one finds many central truths about how our political debates and media discussions function.
Looking beyond how corporate media pilloried Democratic activist group MoveOn over user-submitted (and never-published) video, Greenwald gives a maddeningly extensive history of corporate media compliance with right-wingers' Nazi smears, and simultaneous reprobation of even spurious such instances from the left.

It never ceases to amaze me how hateful and angry the liberals always seem to be. I would have thought they would have gotten happier after getting one of their own elected, but they seen to be even more ticked off now. If you say somthing about Obama's birth certificate, they get angry and call you an idiot. No discussion, just straight to the nasty labels. If you mention Limbaugh, they get mad and yell "he's fat, really fat!!!" Then they say that everyone who listens to him is an inbred hillbilly with downs syndrome or somthing. If you really want to piss off a liberal, just mention Sarah Palin. All you have to do is say the name and they clench their jaws and fists, stiffen up and begin breathing heavily through their nose.
This level of hatred and anger must be indicitive of somthing. Is the left privatly aware of some flaws in the liberal ideology and try to cover it with vitriole? Does the liberal side just attract a–holes? What is the deal? Inquiring minds want to know.
