Sir, - Witness: a great hatred, a programme transmitted by Channel 4 on October 15th, was seemingly intended to advise about (a) anti-Semitism in Ireland; (b) a pogrom which was deemed to have taken place in Limerick in 1904; and (c) the assistance which Irish elements rendered the Luftwaffe in its efforts to destroy Belfast during the second World War.A modicum of research could have conveyed to the author of this disgraceful presentation that Arthur Griffith was not an antiSemite. However, he did trenchantly denounce money-lenders, who in the early part of this century were exclusively Jews.Members of the Irish-Jewish community who befriended Griffith included Dr Bethel Solomons, Dr Edward Lipman, Jacob Elyan, Philip Sayers and the Dublin solicitor Michael Noyek. Solomons, a world-renowned gynaecologist, contributed in 1910 to the purchase of a home as a wedding present for the penniless Griffith, and for many years and to the end Noyek was his most trusted political lieutenant.Chambers Twentieth Century Dictionary defines a pogrom as "an organised massacre, orig. (late 19th century) esp. of Russian Jews". Mirabile dictu, the Limerick "pogrom" was concluded without any loss of human life.The clumsy attempt in the programme to link the wholesome organisation, founded and inspired by Arthur Griffith, with the villainous Nazis of a later generation is both grotesque and despicable. - Yours, etc.,Conn Sheehan,Morehampton Terrace,Dublin 4.
