Glenn Greenwald in Salon:
I think Jon Stewart is one of the most incisive and effective commentators in the country, and he reaches an audience that would otherwise be politically disengaged. I don't have any objection if he really wants to hold a rally in favor of rhetorical moderation, and it's also fine if, as seems to be the case, he's eager to target rhetorical excesses on both the left and right in order to demonstrate his non-ideological centrism. But the example he chose to prove that the left is guilty, too — the proposition that Bush is a “war criminal” — is an extremely poor one given that the General in charge of formally investigating detainee abuse (not exactly someone with a history of Leftist advocacy) has declared this to be the case, and core Nuremberg principles compel the same conclusion.
Leave aside the fact that, as Steve Benen correctly notes, Stewart's examples of right-wing rhetorical excesses (Obama is a socialist who wasn't born in the U.S. and hates America) are pervasive in the GOP, while his examples of left-wing excesses (Code Pink and 9/11 Truthers) have no currency (for better or worse) in the Democratic Party. The claim that Bush is “a war criminal” has ample basis, and it's deeply irresponsible to try to declare this discussion off-limits, or lump it in with a whole slew of baseless right-wing accusatory rhetoric, in order to establish one's centrist bona fides.
