Robin often displays unusual confusions. I think that stems from a reliance on his explicit memory over implicit memory. If he doesn't have a theory to account for why society fails to distinguish songs by whether their lyrics are fictional, as we do with literature, then he considers that a puzzle to solve, even if he's never wanted society to draw that category to aid him in selecting songs.

So when Robin asks, "Why do we appear to value X more than Y", he's not making any claim about how he feels about X and Y. He disregards his feelings and intuitions, because they would mask opportunities to improve his explicit, formal, verbal, theoretical understanding.

This distinction between questions as a tool to point out when the audience is wrong and as a tool of apolitical inquiry closely mirrors the difference between questions as requests for favors and questions as inquiries. It's also similar to questions as argumentative challenges vs questions as inquiries.
