No, I'm sorry, they were not meant to be too clear; or was I in any way trying to bring you to task. Just the way I write my posts sometimes. I am sure the right person read it. You're doing a superb job. I suppose there must be some satisfaction in keeping an argument going when you know precious little about the subject. And not talking about you. I have asked students to debate using that technique. Not quite devil's advocate is it? Sort of bluffing technique.
