Written to The Boston Globe in response to Jacoby's March 11 editorial

I agree with Jeff Jacoby's March 11, 2009 editorial "History's Oldest Hatred." His article was flawless and his comparison to the Jewish festival of Purim well taken as it celebrates, in ancient history, the foiling of a Persian plot to kill all the Jews.

I once, many years ago, viewed the PBS documentary "The Longest Hatred." It explained the historical progression of Anti-semitism but began mostly with early Christianity. The truth is, the etiology of Anti-semitism is even further removed from that as the Jew has so often, even in ancient history, been the other. The uniqueness of Anti-semitism as he says is its protean quality and its ability to evolve over historical time.

He is quite correct to say it endures as an "obsessive and indestructible hatred" the lethality of which has been its legacy for so many Jews. The Jewish people have been condemned to this fate but have endured. It is why, though, ever vigilant will always be my motto.
