Sure. There is singular truth but often times it isn't taken into consideration enough. Otherwise, why do people keep spamming with distorted ideals?
I think moral relativism becomes a sham when one takes into consideration of the entire world itself. Like when your ideas are conventional but some people say that you aren't that open enough to other possibilities, you kind of never concluded about the world as a whole but rather you conclude based on what you're enclosed in.
But hey! It's also logical to say "Why care about what others' believe when you should be believing in yourself because you aren't them anyways?". Just ask yourself: Are you that 'self'-ish or are you that worldly? You might answer this yes/no choice well, too.
This is just my opinion here but if you don't understand me, don't force it.
