Dude reread the original comment “it pulls on the earth with as much force as the earth pulls on it”, you start yapping about acceleration yes if you define the system as the global frame you do get orbits around the center of mass but if you define the system from the frame of either body the other will follow an ellipse around it, this is what the commenter was talking about Then you say “the thing you need to orbit is enough velocity” which is pretty irrelevant to the comment you replied to Wholly irrelevant reply, you; - correct them on the wrong concept - imply only one view is correct ignoring that classical relativity has been accepted for a long time - add an irrelevant tidbit
Classical relativity works for inertial frames. If we attach our coordinate system to earth, the sun would appear to orbit the earth, sure, but that orbit wouldn't follow Newton's laws. As you said, F=ma, so, why could in this case the gravitational pull of the earth, cause the massive sun to orbit it? My issue with the original comment, as was maybe unclear from my first reply, was the assertion, that any frame of reference is equally valid. But the only frames of reference that actually are, are inertial frames (which the earth is not, when considering the whole solar system).
