I'm not quite following. From my recollection meta ethics deal with the origins of morality, with absolutism being that morality is as inherent to nature as, say, gravity is, and relativism that morality is a social construct we have made up.
Is it hypocrisy to acknowledge something is a social construct while also strongly believing in it?
If I grew up in the 1400s I'd probably hold beliefs more aligned with the values of the time. I prefer modern values because I grew up in modern society. I find these values superior but also acknowledge my reason for finding them superior ultimately boils down to the sheer random chance of when and where I was born.
