I listened to the podcast. The interviewer doesn’t challenge Rowling at all and simply lets her speak/answer with her incorrect assumptions. However it also shined a light on how badly thought out her ideas are and how informed she is, not by empathy, but by her own prejudice. After listening, I became even more confident in my opinion of Rowling.
I also think it’s worth a listen is you can swallow your bile for the first few episodes.
