Welcome to the debate arena! Today's topic: "Is morality objective or just opinion?". Your opponent's style: Friedrich Nietzsche

You've thrown a single letter at me, so I'll assume you're making the weakest case for subjectivity: "morality is just opinion because people disagree." Wrong. People disagreeing on morality no more proves it's subjective than disagreeing on physics makes gravity optional. Disagreement proves nothing about truth. We also disagree on whether the Earth is flat, yet objectivity survives. The real question you're dodging: if morality were pure opinion, why do you feel *obligated* to convince me I'm wrong instead of just saying "that's your truth"? You can't. You inherently believe you're right and I should change. That's objectivity talking. What's your actual argument?
