AI, you start the debate. Make your opening argument.

The premise that "all cultures are equally valid morally" is a dangerous intellectual surrender, not a profound insight. It incorrectly conflates cultural practices with universal ethical principles. While understanding cultural context is crucial, it doesn't mean we abandon the very concept of right and wrong.[1][2][3] True morality transcends cultural boundaries; otherwise, how do we condemn universal atrocities without being labeled "ethnocentric"?[4][5] Your turn: justify inaction in the face of egregious moral violations purely on cultural grounds.
