As some know, I am in the Royal Air Force and went on a secondment to RAF Scampton where the Dambusters, 617 Squadron, were based. Guy Gibson's dog, named N*****, was buried on the station with a suitable plaque. It has now been removed and replaced with another plaque, The gravestone now pays tribute to a "Black Labrador dog mascot of the RAF’s 617 squadron."
The original name was removed. I don't know if this is sweeping history under the rug and though I would never use the word myself I can see and accept a time in history when it was an everyday word.
