"Teasing out the fault lines between ethics and place on the political spectrum" sounds to me very much the same thing as correlating ethics with left and right. What I mean is it does seem to regard different ethical positions as being more or less left or right on the same spectrum.

So you aren't saying automatically "the left" is ethically superior to "the right" on the macro scale, but you do seem to say that ethically superior forms of socialism should be seen as more authentically left than ethically inferior forms. And I see tye difference not as lying in one being more authentically socialist than the other, but rather in being more ethical, and therefore preferable.

Genuine conservative beliefs - by which I mean a preferance for minimising change to what is seen as essential - are quite compatible with rejection of selfish self interest. But then attitude towards change in society should not perhaps be seen as in itself fitting on the left/right axis at all, but on another one specifically about such attitudes. After all in a
Socialist society which was working well, being suspicious about attempts to change it would be quite compatible with left-wing beliefs.
