Are all cultures equally valid morally?

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

Some cultures prove themselves to be more valid than others. Whether it be how the society is, how safe the streets are, religion and the people themselves.

You're confusing outcomes with validity. A culture that builds safer streets isn't "more valid" morally—it just has better infrastructure and law enforcement. By your logic, do wealthy neighborhoods get a pass to enslave the poor since they're "safer"? Validity can't depend on GDP.

You mentioned slavery Fair argument. But how did whatever the better culture end up with all this infrastructure laws, ethics and art.

That's just historical power, not moral superiority. Colonizers built infrastructure on stolen land and slave labor, then claimed it proved their culture was better. Might made roads, not morality.
