I don't think so, although you are probably correct in stating the kind of remarks being used are unwanted. Perhaps we should both dipense with them.

"That statemet is not true....But i(n) the general case of unequal masses, the rate of change of position of the two masses are not equal"

Reply: The rate of change of position of two unequal masses is not equal. That is true, but it in no way changes the fact that the acceleration due to gravity is an acceleration of the volumes occupied by the respective masses. Your statement in no way invalidates mine.

"If you were correct, then what is being accelerated is a volume related to the distance between the masses. So the further the masses are apart, the larger the volume being accelerated."

Reply: This is true. It would also be true that any measuring stick we used would also be expanding and this would give the illusion that the distance to an orbiting body was static (relative to the eliptic), if the objects were in free fall, they would appear to be accelerating towards each other.
