Debates are silly and accomplish nothing other than entrench a losing side deeper into its position.
Yes, I'm beginning to come to that conclusion. I'd rather see a respectful discussion and exchange of ideas, where both parties are seeking the truth and not attempting to "win" or "overcome" the other side. This exacerbates the dialectic of extremes, where the sides over-react to one another, get entrenched in their positions, and often error in the opposite direction.
If I had to structure a "debate", I would make it so that it would be alternating 2-minute segments of talking, more an exchange of ideas, a back and forth, than some kind of competition or contest, putting on display the worst qualifies of sophistry.
Very few people are open to looking for the truth but simply want to be proven right.
