There is a lot of confusion about what is meant by “moral relativism” and “moral objectivism/realism”
“Subjective” and “objective” tell you about the source of the truth maker; i.e. what makes something true. Is it the beliefs of the subject (the person’s mind) that make it true, or is it an object in the external world? My belief that homemade vanilla ice cream is the best ice cream is what makes it true that homemade vanilla ice cream is the best ice cream for me. In contrast, the curvature of space-time is what makes gravity true – not just for me, but for everyone. Gravity is true regardless of what I believe about it.
