Last word or not is your choice (now:).

I have three different, and possibly equally unpalatable responses to the undertones in your post, but I will not post them because they would probably be taken as either petty, or defensive or "last word" material.

They would not be. They would be, or could become with work, entirely serious and considered responses to both those undertones and the (IMO) single angle of the singular subject of this thread. But I will save them, perhaps, for another day and another thread or maybe another place. Because I have detected that you are unwilling to continue. (Intuitive ain't I :) (Please see the funny side and self-deprecation in that remark.)

As with all this type of discussion, I have no desire to "convince you" to change your mind. Foremost is to either change my own mind, or ratify my own conclusions in the light of others consider opposing views. Second-most is to, perhaps, provide others with an alternative viewpoint.

Finally, I choose the people I take the effort to argue with because I respect their record, experience and point of view, even if I disagree with it. There little or no mileage in pursuing extended conversation with those with whom you agree. There's nothing to learn. And, as I've said a couple of times before, my reason d'etre for coming here and sticking around is for me to learn.

I sincerely thank you for you're interactions with me, in this thread and others. I always come away from them having either learnt something new, or having reinforced my previous conclusions. Both are equally valid, and valuable. To me.
