Sir, The announcement by the NUJ that they have banned (Issued Guidelines) the words tinker, knacker, trader, itinerants, shows once again the hypocrisy of our guardians of democracy. Remember their bleating about Section 31 and free speech. Even worse is the lack of comment by our politicians of all parties, but particularly Fianna Fail, Fianna Gael and the Progressive Democrats. Yours, etc., Loreto Avenue, Rathfarnham, Dublin 14.
