From their perspective, it may well be - not everyone subscribes to moral relativism; it's part of those axioms.

But even then, "Based on my values ..." is implied. It just comes with an assertion that those values are universal (which, if you're a cultural relativist, you'll treat the same as well, recursively).

Based on which values though? I don’t think they should go unstated, because if I don’t hold the same values then arguments holds no water with me.

A particularly annoying one is when people lie about their values or worse claim that their argument doesn’t stem from their values (are they embarrassed?), it’s purely “rational” and anyone who doesn’t agree is pc virtue-signalling cuck who is blind to reality.
