Political correctness is on the move again. The pc form of "Snow White And The Seven Dwarves" is now "Snow White And The Seven Gnomes" apparently because some people found "Dwarves" offensive to the short people to whom this word refers. It remains to be seen if it will hold, however. I agree with those linguists who say that popular preference always determines which words win out in the end. ;)
