The world has moved on since the heydey of the empire, when British was best and the rest of the world was a rag-tag collection of races to be reduced to a stereotype.
Whether he is telling a group of British students during a 1986 state visit to China that they would become "slitty-eyed" if they remained any longer, or having a pop at the Scots for being drunkards, Prince Philip has a put-down for everyone.
He probably fancies himself as a bit of a rogue and the last of the straightshooters. Clearly he doesn't care and certainly doesn't care to change. His appalling attitude to the photographer at a recent photo shoot shows a large degree of contempt for those just doing their job.
Does it matter? Of course it does - far too many people put up with his buffoonery and show undeserved deference. It is time he stepped out of the royal bubble and into the real world.
