Okay, I was initially wrong. What you're arguing is "ethical sentences serve merely to express emotions" (i.e., Emotivism). Am I correct?

However, this is still a form of Moral Anti-Realism because those moral utterances do not reveal objective moral facts in a purely physical world. Those ethical sentences lack truth value because they do not express genuine facts beyond feelings of disapproval or approval.

I feel as if we have enough empirical data to know the material world is blind and indifferent, so this fact would stand regardless of not being able to attain objective knowledge of morality.
