How wasn't it convincing?
It's pretty obvious that Stewart knew about the rumors. He tried to play dumb, but it wasn't very convincing IMO.
Then the moderator immediately ended the Q&A, which made me think that either A) the moderator
also knew of the rumors, or B) Stewart somehow signaled for him to end it.
No it wasn't obvious.
And the moderator did not immediately end it, he let that kid ramble on for about 2 minutes.
The kid was obviously nervous, but he was persistent and he refused to let Stewart brush him off.
I personally wouldn't call it rambling, but YMMV. Here's the transcript
(with editorial input from me):
Audience member: I wanted to ask you about the last interview on your show, which I think was Louis C.K.
Stewart: Yeah.
Audience member: So from my memory, I think that was after some of the rumors about Louis C.K.’s alleged harassment of female comedians—
Stewart: Whoa.
(To me, I get the vibe of "Whoa, let's not go there", not "Whoa, I'm shocked to hear this")
Audience member: —had sort of started to come out.
Stewart: Wait, what?
(He's feigning ignorance, IMO -- especially when his subsequent comments are taken into account.)
Audience member: It was after Jen Kirkman had talked about her knowledge of Louis C.K.’s alleged harassment of comedians — at least people interpreted it that way — and an article on Gawker, I believe, about it. I just wanted to know — if this is the first you’re hearing of it, maybe I already got my answer, but there wasn’t discussion about this on the show.
Stewart: [laughs]
(Nervous laughter, IMO.)
Stewart: Wait, wait, wait. I’m a little lost. So the internet said Louis harassed women?
(Trying to minimize the accusations by blaming "the internet". His defensiveness here speaks louder than his words.)
Audience member: So, there was first a Gawker article and then a couple of tweets by people—
Stewart: [laughs] You know who you’re talking to, right?
(His tone here is a mixture of condescending "I don't read the internet" and "I'm friends with Louis", with a dash of the "Do you know who I am?" card. Again, his defensiveness speaks louder than his words.)
Audience member: It’s a fair point that internet rumors are not court cases or anything. I just wanted to know if there was any sort of discussion about that on the show, if that was a thing on your radar.
(Good job here, sticking to the point.)
Stewart: No. I didn’t see the tweets.
(Notice how Stewart is now being VERY careful with his language. "I didn't see the tweets" is NOT the same as "I have no knowledge of those rumors".)
Audience member: Or Jen Kirkman’s podcast about—
Stewart: I apologize. I’m not that connected to that world.
(Again, "that world" has a patronizing tone to it. Trying to brush it off because it comes from the internet.)
Stewart: I don’t know what you’re talking about but — I can’t really answer. I don’t know what to say.
(Again, I think he's choosing his words carefully. He's saying "I don't know what you're talking about" in reference to the tweets and the Jen Kirkman podcast. Otherwise he would flat out deny that he'd ever heard the rumors.)
Audience member: I think a lot of people at the time didn’t know what that was. Again, the internet is not for sure, but there have been comedians who have taken strong stances on Bill Cosby without certain knowledge, from Bill Maher to Hannibal Buress. I just wondered if you could talk about the role of comedians—
(This was maybe too wordy, but it was well thought out.)
Axelrod: But as you pointed out, the Bill Cosby case actually is a legal case.
(Axelrod is obviously trying to bail out Stewart here. Is it because he also doesn't want to expose C.K.? Or is it because Stewart is kicking him under the table?? Or is he just upset that his friendly and fun Q&A has suddenly taken a dark turn?)
Audience member: It is now but it wasn’t when Bill Maher and Hannibal Buress were talking about it. Maybe you can speak to the role of comedians—
(This was an excellent response, IMO. The kid thought on his feet and deftly parried Axelrod's thrust.)
Stewart: All I can tell you is I’ve worked with Louis for 30 years and he’s a wonderful man and person and I’ve never heard anything about this.
(Finally! A denial. Hmmm, but what exactly was he denying?)
Stewart: We’ve all known Bill Cosby was a prìck for a long time, so I don’t know what to tell you.
(This response is a little odd because he's associating Cosby's acts with the fact that he was a prìck, thereby implying that "wonderful" people can't be sex criminals.)
Stewart: But I didn’t know about the sexual assault—
(Aha!! More evasiveness!! This is classic Clintonian "I did not have 'sexual relations'" stuff.)
Audience member: Not sexual assault, but—
(Way to go, kid! Stay focused on the topic and don't let him off the hook.)
Axelrod: Sir, appreciate your question. Thank you. And let’s say thanks to Jon Stewart.
(Oof.)
