Yes, I created the pointing table moving example. *You* responded by postulating "only if there was a mark on the wall." Then you dismissed my objection because "if it did have such a mark then the room would no longer have cylindrical symmetry." I.E., *you* invented the part of my argument that you later refuted. This was the straw-man point.

But then they wouldn't be seeing the same thing. One would be on the left, while the other would be on the right. One would have to lead with the table, while the other would have to follow. They would know which one was the leader and which one was the follower. Their identities would diverge, by your definition. Again, the example does not prevent the divergence of perception that you require.

Yes, we agreed to that before the symmetrical room example. I believe that you asserted that the symmetrical room would prevent such divergence. I believe that I have shown that it does not. Are we now agreed on this latter point?
