I was surprised to read Ian Jack's musings on the racial origins of Cliff Richard (7 July). I am always suspicious of people who show an unhealthy interest in the racial (or class) roots of other people. Lofty liberal excuses don't convince in this case - this smacks of the bullying excesses of gay "outing" - or worse. I hope this is not the start of another perverse media trend. These days, you never know.
