"Anonymous. How can I turn my body without turning my shoulders."
With practice. Remember that in dance language, your body is your hips.
"Are you sure that's what you meant."
Yes
"Are you deliberately trying to incorrectly aligne your spine."
No, I am rotating around it, I am not bending it backwards like so many do. The human body is designed to do what I do. Since it is a rotational movement, the body weight remains aligned with the spine - this avoids the risk of injury involved in bending the spine to misposition the weight. You are free to turn around your spine without injury, but you need to be very carefull of bending it in the arched back way.
"Are you aware that the knees are veered into each other and that you are going to use an inside edge on the second step. If you continue walking you will turn a complete circle. But more importantly the placing of the second step is preditermined by the first step which is in CBMP as would the third step which would predetermine the fourth step if we kept walking."
What's your point?
My argument is with your distorted topline cause by allowing your shoulders to rotate into your partners' space, not with your foot placement.
Perform the step properly and your right side will arrive first, but your partnership will still be built around a left side stretch in the topline - your right side leads the movement, but your left side leads in the hold. You musn't loose the left side stretch and orientation of the hold unless you plan to switch your partnership offset to the other side.
