The practical payoff is what matters: a person who can reason clearly about a goofy topic can reason clearly about a lease, a ballot measure, a medical claim. If we only debate pre-verified propositions, we never practice the skill that actually gets used. My opponent's purple example is fair, but notice it's about an empty claim, not an undignified one. That's a real distinction. So sure, demand reasoning, demand structure, demand evidence where it applies. Just don't confuse a silly title with a missing argument. The habit of arguing well about anything is the whole point.
