Edward, I received your private e-mail to me, and I am sorry you are taking that attitude, that you will not expand upon what you wrote to the list. I asked in good faith, assuming since you brought it up you wouldn't mind discussion. Nothing I wrote indicated that I wanted to "debate" or argue; I don't understand your threat to unsubscribe from the list. I believe that educators are ethical, dedicated people who try to teach the very best "truths" and understandings that they can, and want their students to learn to evaluate their lessons for themselves, with the tools of critical thinking they are or should be receiving in school. If the matter is closed for you, as you indicated in your note to me, then it is closed for me, also. I do not engage in contentious private e-mails from this list or any other, so my reply to you is a reply to and through the list. Sharon
