A few thoughts:
- At 30:00-ish, Bart rehashes the tired old trope about the Apollo 11 crew being in "low earth orbit" despite his claim being debunked, dissected and dismantled thoroughly over the past two decades. The poor guy just can't bring himself to admit defeat on this easily disproved allegation.
- Rogan is not very good at steel-manning an argument. His biases from 15 years ago still hinder his ability to think rationally on the topic, and he has a bad habit of making false, pointless concessions.
- Despite supposedly doing a 180 on his moon landing beliefs, Joe is still of the opinion that some of the official NASA photos were "faked". Naturally Bart seizes on these admissions like a pit bull on a pork chop, as the lisp and spittle intensify.
- Despite 2 and 3, Rogan does manage to challenge Bart on several occasions, clearly annoying him in the process. Bart is not used to this, as he typically only accepts interviews with "friendlies" who let his asinine assertions slide while they serve up the next volley of softball questions. At one point he becomes so flustered that he asks Joe (essentially) which side of the debate he's on.
