Well, I now have lots of replies to work through. Many of them provide excellent evidence of precisely the sociological trend to which I am attempting to bring attention.
Since beginning this thread I have been attempting to clarify my thoughts on the matter, so I have not been replying. The tendency to dismiss, misrepresent and ridicule the notions which I have presented are to be expected of course. No culture easily accepts a critique of its own particular style of collective ignorance and bias confirmation (and they all have one, as do all individuals - as above so below).
Watch this space.
