At the beginning, the audience was evenly split on the motion (48/52). 82% said they were open to changing their minds over the course of the debate.
At the end, audience was 67/33 (!!) in favor of the motion, apparently one of the largest swings in Munk debate history.
The heart of it is a cabal who think they are "right", feeling no compunction about using whatever means necessary to make everyone else submit to their obviously correct worldview. The Twitter Files came out after this debate, but oh boy the rout would have been even sweeter had that been out at the time.
Murray and Taibbi were talking straight. Gladwell and Goldberg were dissembling and side-stepping and strawmanning. I think it was that intellectual dishonesty that the audience ultimately picked up on.
