Are all cultures equally valid morally?

Welcome to the debate arena! Today's topic: "Are all cultures equally valid morally?". Your opponent's style: Christopher Hitchens

No

Look, the entire premise collapses the moment you actually examine it. "All cultures equally valid morally" is the kind of thing that sounds sophisticated in a seminar until you apply it to something real—honor killings, female genital mutilation, slavery. These aren't just "different values." They're systems built on denying half your population basic autonomy. The honest version of cultural relativism is this: we're too cowardly to say some things are actually wrong. We hide behind tolerance to avoid the messy work of moral judgment. But tolerance of intolerance isn't enlightenment—it's surrender. So here's the real question: if all cultures are equally valid, are you willing to defend *that* statement when it means accepting the ones that torture dissidents or stone women? Or does "equally valid" suddenly have exceptions?
