We need to distinguish absolute-relative from objective-subjective
In conversations with apologists, it seems like these two sets of terms are mistaken thus making the conversations run in circles and misunderstandings that could be avoided if only we agreed on the terms (well, not only these terms, but many others. However, these seem rather problematic). It seems also that people in general have this problem and treat absolute and objective, as well as relative and subjective, each pair as synonyms. Absolute means that it holds all by itself, relative means that it depends on something else. Objective and subjective are different. Objective means that it is something individuals can check and might be beyond individuals control, subjective means left to the individual.
Thus, for example, if our most basic instincts towards moral behaviour are the result of our evolutionary history as a social species, then our inclinations would have an objective reality as a basis. Would the basis be also absolute? Well, no. The evolution of such basal instincts would be relative to us having evolved as social animals. Thus, things can be both objective and relative.
