Palin needs to get up to speed on this kind of thing if she hopes to broaden her appeal enough to mount a presidential bid.
Her appeal has nothing to do with this kind of nuances. Most Americans would agree that a violation of Free Speech is condemnable regardless whether from the government or the media.
The spirit of the constitution is protection of all speech, especially if one side finds it objectionable. When Perez Hilton, Kieth Olberman etc spout their hypocritical selective indignation and hate-filled diatribes (including digging into parental divorce records) they are behaving despicably. But they are practicing free speech, not "violating" it. This is not "nuance," it's an essential distinction.
(Beside that, defacto the media is argueably now a branch of Government... though not "technically".)
That may be true, but the only cure for that is the free market of ideas. If speech is not being suppressed by the government, it's ignorant to invoke the 1st amendment. That's OK for a beauty queen, or a voice on the internet, but not for a serious candidate for president. And Palin WILL have to broaden her appeal beyond what she has now if that's her intent.
