First off, you are once again dismissing out of hand Jonathan's examples, which he described as including a body twist in the basic hold.
"CBMP is a Foot Position"
This is a classic case of the difference between the quite limited presentation in the book, and the much more involved reality of what a student is eventually trained to do by a live teacher.
Yes, CBMP is a foot position. But putting your foot in that position has an impact on the configuration of the torso! And when we step into the across in CBMP position of a promenade while keeping our upper body aligned to our partner, the necessity of some twist in our spine is impossible to ignore.
"That leaves CBM. In CBM according to Moore " Care must be taken not to turn the shoulders independently."
That does no mean that shoulders and hips will always turn in exact unison. I n fact, in the paragraph right before your quote Moore suggests that one might feel the movement of forwards turns initiated in the shoulder and that of backwards turns initiated in the hips. Or in more modern usage, reverse turns are commonly taught with the rotation of the lower body commencing a little sooner than that of the upper.
You must also give due consideration to Moore's stated concern: "or an ugly dipping movement will result". If a dancer under their teacher's skillful guidance incorporates an appropriate degree of spinal twist in assorted places and does not suffer an "ugly dipping movement" then they must not be committing the particular fault that Moore was warning about.
"For me I am taught to drive the spine in the direction I am going."
Me too - but drive and rotation are two different variables. There's a far simpler-to-apply rule for keeping them in proportion: if you are moving forward, your forward movement must be great enough in comparison to your rotation that no part of your body is allowed to move backwards in space. If that occurs, and perhaps your left hand goes backwards then your rotation has overwhelmed your movement,
"The main part of my argument has always been that the spine , which is our centre does not get twisted but remains as our driving force in the direction we are going."
And the main reality of dancing has always been that the spine does twist in many situations, even as it drives forward.
You can refuse to learn about this aspect of dancing for the rest of your life if that's what you choose, but the rest of us are happy to keep learning such details from the best teachers.
