Moral realism and subjectivity
Moral realism and moral subjectivity both arise naturally from the goals-
Moral realism
If I have moral goal GM, then it is true that I (morally) should do action X (that promotes GM). The moral goal is mutual thriving, surviving and/or reproducing.
Moral subjectivity
Moral principles come equipped with normative pressure, since each is a method of achieving mutual fitness, and there is evolved normative pressure to achieve fitness (thriving, surviving, reproducing).
The moral agent can only act upon this normative pressure if they endorse the particular method, or domain of methods, for achieving mutual fitness. I.e., if I do not think a principle is legitimate then I will reject it as illegitimate.
In practice, the domain this applies to is patriarchy. The goal of patriarchy is reproduction, which is mutual, but on men’s terms, at women’s expense, which is not compatible with fairness, equality, women’s autonomy, etc.
