True. But its not just me. You're recommending a particular way things should happen in public so an explanation of who you believe should be exceptions, and why they need to be exempt is surely owed - not to me but to the stakeholders - including EH and Historic Scotland if theyre looking. How can they learn and adapt, other than by hearing your explanation?

But what's wrong with having different opinions? We don't have to call a halt to the discussion at all.

I think you want to stop the discussion because you don't want to elaborate on the who and why.

If you don't think it's black and white, then why not explain your more nuanced greyish view?

You might educate a few other people even if you can't change poor Nigel's mind.
