Well, my above reply was a bit tongue-in-cheek. My concern for other things in general is just as complex as my morality and it contains many meta elements such as "I'm willing to modify my preference X in order to conform to your preference Y because I currently care about your utility to a certain extent". On the simplest level, I care for things on a sliding scale that ranges from myself to rocks or Clippy AIs with no functional analogues for human psychology (pain, etc.). Somebody with a literally wildly differing reflective preference would not be a person and, as you say, would be preferably dealt with in True PD manners rather than ordinary human-human altruism contaminated interactions.
