If morality is subjective...

[Angrboda]

Morality is contingent, but not subjective. It depends on things like human nature, and the family and community we learn our morality from. If I grow up in a racist family, there's a good chance I will end up racist, too. That's a contingency; I didn't decide that I would have that influence on my morality, nor do I really have much say in how I react to that environment, whether I rebel or not, it's a matter of contingent factors in my life. Morality is part human nature and part inheritance. If I grew up in a country where racism was accepted, I would develop a different morality than if I grew up in a country that abhorred racism. It's contingent, not subjective.
