You can claim that subjective attitudes are still part of reality ontologically , but the point is that they function differently epistemologically . Opinions and beliefs and for the and falsehoods are all made of atoms, but all function differently. There are potentially as many subjective attitudes as there are people, and they are variable across time as well. The arbitrariness and lack of coherence is what causes the problems. Objectivity is worth having in ethics, because a world in which prisoners have done something really wrong, and really deserve their punishment is a better than a world in which prisoners just have desires the majority don’t like.
