I think much of the reason they let her just talk is the whole steel man strategy that KK encouraged- they didn’t need to grill her or make her squirm like a press interviewer would, as she exposed the glaring flaws in her own arguments merely by continuing to talk anyway.
I’m glad they were open to her perspective and gave her the space and time to just look like she did, as there can be no accusations that anyone twisted her words or that she was tricked or blindsided. It was a hugely charitable airing of her views, whereby she was free to push the direction in whatever way she chose frame her arguments in the best light. So I guess that was it..
It was interesting that, as a seasoned podcaster and comedian, she complained that doing interviews was different from writing the book as she didn’t have time to think about her arguments in the moment, especially given that she requested to be interviewed by them. This suggests she knew how she she was coming across and had some regret, and I think at that point, she would have been very happy for KK and FF to have wrapped things up (as she couldn’t bring it to a close without flouncing as it’s not her show).
I think their strategy of simply not wrapping it up and continuing to let her talk herself into the ground when she expressed frustration that she wasn’t coming across better was far more effective than grilling her about her past antics. It was the whole ‘more sunlight’ strategy, which, as we all know. can work incredibly well.
Also, they are running a business, and this video will obviously do really well as people on both sides of the debate will be talking about it, so the cross-pollination is good for them (as they still get paid whether people watch the video because they love it or hate it). So the more of a hot mess it is, the more people will talk about it.
Plus, they don’t want to put off other guests from the other side of the political spectrum who might want to approach them in the future by getting a reputation for aggressively blindsiding interviewees, especially when it wasn’t necessary to expose her hypocrisy or muddled thinking - she didn’t need their help with that.
