I don't see that there is an argument - rather that a separate chain of discussion has started. It's fair to then say "well that's all fine but what I was thinking of was X" which is what I am reading. I think that there is a big difference between frames of Einstein (I don't understand these) and frames of reason and perception (I don't understand these either) but I do see that there are two different things!

Like I don't understand either Australia or Argentina.. but I know that they are not the same!
