Contrary to what a few individuals have said, I have not removed any comments from the Blog. This week, or ever. I'd really rather avoid that.
We're having some spirited discussions, and that's fine. To those of us who are more spirited than others: Can you please watch the language and especially the name-calling? That's not getting us anywhere. Make your point and be mature about it. When most of us are listed as 'Anonymous' on here, it's very tempting to send off an anonymous flamer of a reply. Try to avoid that temptation.
Be like Mr. Rogers: Take the high road. Or else your trolley-riding priviledges will be revoked.
And to everyone else: Thanks for all of your helpful insights and advice about these questions.
