“Hence, if anti-realism is true, it's no more rational to criticize either man for his belief about murder than for his belief about the flavor of ice cream.” What proposition are you representing with the label “anti-realism” here? If anti-realism is about stance independence or dependence, the consequent doesn’t follow. Subjectivists can criticize others for not sharing their views without being irrational. They just can’t base the criticism on stance-independent norms. E.g., “your stance on murder will have the following consequences, which you claim you don’t want and will not occur,” or “your stance on murder and your stance on [something else] are logically contradictory.”
