We probably have different takes on Stewart (I haven't seen the episode, and I would prefer not to analyze Sullivan and Bond just on the basis of paraphrase). But I have seen a few clips of "The Problem with John Stewart," and as a liberal, I find his recent stance problematic.
It seems to me that rhetorically the recent Jon Stewart is closer to Bill Maher than to Stephen Colbert or Trevor Noah (both of whom contributed to the previous Jon Stewart persona), for example, with an emphasis on outrage rather than clarity. I think that the "new" Stewart feels called on to make white liberals comfortable with their whiteness, much as Bill Maher does, by suggesting that he (both Jon and Bill) are more "open minded" and less dogmatic than their fellow liberals. He wants to make white liberals feel that their outrage against philosophers like Sullivan is justified, but more importantly that white liberals don't have to turn the mirror toward themselves, because they are busy dismissing the "faux liberals" that Sullivan represents in Stewart's recreation.
