To clarify ~~ I know this is a serious topic: and I was there not failing to take it seriously. I was simply replying to your point that all the authorities cited by Keith had taken trouble to distance themselves from any sort of underlying racial connotations. I could have written,

"It was predicable that they would do so, to obviate any possible accusation of prejudice on their own parts";

but it seemed to me more effective to cite Miss R-D's well-known remark at the Profumo trial [it is even in the Oxford Dict of Quotns!], making my point referential rather than declarative, thus calling on a certain degree of momentary consideration and recognition from the reader. It was over-earnest and unnecessarily hostile on your part, to dismiss that so contemptuously as my merely being 'clever-clever'.
