What happened (more or less): David Benatar, having asked a question of Martin Hall, insisted on a response to that question, to inform what question to ask next. Martin refused, asking for all of the questions at once, before responding. The Chair - Pumla Gobodo-Madikizela - intervened; David insisted that he be allowed to proceed as per "Socratic method" debating, subsequently granted by Martin.
What was seen by black, mostly "non-academic", members of the audience*: A white male professor dismissing / ignoring the intervention of a black female colleague [who had situational authority, as the Chair, which was not respected].
What was seen by white "academic", mostly male, members of the audience*: An academic standing up to the bullying of a managerialist / Bremnercrat / DVC who had no regard for intellectual process.
What I saw: A sports match, with a deeply divided audience each cheering on their player when a point was scored. Ending without result, without resolution.
