Can you tell me who specifically came up with X and when? PM if you like.

Just me specifically. But I had better put the disclaimer that I considered X' that seems to fit the censored context, assuming that I have correctly mapped Paul's 'indirect normativity' to my informal conception of the context. I am of course curious as to what specifically your X is. I am wary of assuming I correctly understand you---people misunderstand each other easily even when the actual arguments are overt. If you have written it up already would you mind PMing it?
