I’m not sure if there’s standard jargon for “all moralities are of equal merit” (I’m pretty sure that’s isomorphic to moral nihilism, anyway). However, people tend to read various sorts of relativism that way, and it’s not uncommon in discourse to see “Cultural relativism” to be associated with such a view.
What I was thinking of was postmodernism—in particular the sometimes-fashionable postmodern conception that all ideas are equally valid. It is a position sometimes cited in defense of the idea that science is just another belief system.

Believing that all moralities are of equal merit is a particularly insane brand of moral realism.
