I was so delighted to see this lesson as I rested from my enjoyable labors of the day. A "debate" of art issues with you would be the equivalent of a debate of legal issues between Al Franken and Justice Scalia (with me being in the Al Franken role), so I will just tell you how much I enjoyed it.
Yes, you may be right about a proper "debate," but we could discuss, could we not?
I'm waiting for someone to say, "But you didn't put in my favorite ....." and then I would and we would find out about it.
Meanwhile, I should grade exams (which is much more boring than FR).
