I see, you think moral values have nothing to do with actual beings, and there nature is unrelated to values.
In that case, if objectivists are denying that they hold to any moral truth whatsoever (no moral axioms exist). That would make all objectivists moral relativists. No way around it.
This is partly correct. Moral values are both relative and absolute. The are relative in the sense that they are related to real beings living in a real world and define what is good for them and what is bad. Moral values are absolute in the sense the what will be good for those real beings is determined by the requirements of their nature and the nature of the world in which they live.
Objectivist reject arbitrary moral rules based on someone's whim and the principle that might makes right.
