Jim, My objection is to your initial wording "pulls them around" which implies a *tangential* force (a push or a "pull", a thrust) to the lay reader. Better would have been "pulls them toward the center of the earth."
We certainly agree that an earth-centric coordinate system is best for explaining near-earth orbits. This transitions to a moon-centric system as best for orbits around the moon. Please do not associate me with invention of the "slinch."

But I continue to disagree with you. Jim, we disagree on your initial wording, not of the physics as more precisely worded.
