No, I was trying to figure out how someone can accept both moral nihilism (a view that moral statements do not have truth values, or meaningless, and no act is inherently evil because nothing is evil) and reaction to certain cases. I was not trying to show that he should accept certain action as morally acceptable. Nobody should. The point of the reductio was to be a challenge to MORAL NIHILISM. Moral nihilism is a highly abstract position, may be even inconsistent, while essential badness of certain actions is virtually uncontroversial. My point was to show that self-proclaimed MORAL NIHILISM simply can't be held in such circumstances, not that certain actions are not bad, or may be justified. This is a position some claim is simply IMPOSSIBLE to hold. I was implying as you would claim that he couldn't hold this position, and was moral realist after all. We stared this discussion some time ago in another place, and it was a continuation.
