When I said I'm aware of the subject matter, I was referring to the understanding of the theory, not the label. It seemed to me it would be redundant to simply state the label of the philosophical theory we're discussing to make that point.
So to make my point I mentioned relativism and absolutism instead. After all, since subjective morality means made by men and that it can vary from person to person, then such a morality would qualify as relative in that sense. If the opposite meaning is applied for objective morality, then morality is not a matter of personal opinion but a matter of fact and definitive for everyone, which is therefore absolute in that sense. Hence relativism and absolutism are part of the subject matter.
