I'm not sure I understand this. Are you objecting to my use of the word 'idealized', on the grounds that preferences and facts are different things and uncertainty is about facts? I would disagree with that. Someone might have two conflicting but very strong preferences. For example, someone might be opposed to homosexuality based on a feeling of disgust but also have a strong feeling that people should have some sort of right to self-determination. Upon sufficient thought, they may decide that the latter outweighs the former and may stop feeling disgust at homosexuals as a result of that introspection. I believe that this situation is one that occurs regularly among humans.
