Twilight Hue
Twilight, not bright nor dark, good nor bad.
You'll notice this thread is, perhaps ironically, in a discussion section. So no debating about debate, please.
What are the features of a good debate? I intentionally use the word "good" here, knowing it means different things to different people. Perhaps a good debate, in your mind, is a productive one, one you are glad you engaged in (or watched/heard), one you learned something from, one you felt was a worthwhile use of your time, or some other positive attribute. I leave it to you to explain how you understand the term in context of this conversation.
What are the elements or features of such a debate?
A debate that covers the when, where, and hows tend to be the most useful and practical.
Other debates are more geared for entertainment than anything else. Like many of the smackdowns here.
Both are fine imo depending on the mood.
