I did not accept that my first point was
Tosh & just let it slipaway. I felt that there was no point in continuing to assert that 'concern' added nothing to your clue and was superfluous. I don't have to tell you, an expert, that in a well formed clue every word in the clue should be relevant and, to me., concern added nothing.
AS for describing my point re Chambers as also being tosh, I can only repeat that most serious crosswords do not accept words not in the Chambers dictionary . In fact most serious puzzles make a point of saying that and going further by identifying any clues which may not be in Chambers - the exception to the rule. You're excuse that the Clueless 8 is not serious is accepted and it makes me wonder why you have made so much of my words?
You seem very reluctant to accept that your clue , no matter that it was deemed the best, is flawed and not only is the surface reading ungainly but the individual components are questionable.
If you hadn't taken such umbrage at a gentle criticism there would'nt have been this protracted exchange.
If you could explain your closing remark that 'there is not much point in talking to someone who wilfully misinterprets what you say' How did I do that?
