Not sure how the h-morality vs non-h-morality is related to affect though.
This point is in the context of the linked post; a clearer test case is the opposition between p-primeness and primeness. Pebblesorters care about primeness, while p-primeness is whatever a peblesorter would care about. The former is meaningful, while the latter is vacuously circular as guidance/​justification for a pebblesorter. Likewise, advising a human to care about whatever a human would care about (h-rightness) is vacuously circular and no guidance at all.
In the implied analogy, affect is like being a pebblesorter, or being a human. Pointing at affect-creatures doesn’t clarify anything, even if humans are affect-creatures and causally that played a crucial role in allowing humans to begin to understand what they care about.
