FWIW, I deleted those posts long before I was asked; however, in my haste to return to work, after I pressed 'delete' I left my computer and started to teach. A couple of hours later I got back to my desk and I had forgotten to post the reason for the deletions, so the process wasn't completed. And of course more posts have come in since.
Anyway, no one's going to change anyone's mind here. No more posts on this. Everyone's made their points, and I think both sides' points have their merits. But if it becomes a personal attack against another poster, and you've been warned, you'll be given a vacation. Back to Jaylon...
