Along the way at Z Word, Eamonn characterizes an article by Yossi Gurvitz as follows: [for Gurwitz] 'antisemitism is a non-issue and to the limited extent it exists it's caused by the misbehavior of some Jews'. Clicking through Eamonn's link to the piece in question should satisfy you that his characterization is not wide of the mark.
How, at this very late date in our understanding of the phenomenon of racism, it's possible for a serious person to blame racist attitudes on the misdemeanours of some members of the population group that is their object is beyond me. How, equally, any serious person with any kind of biographical links to the Jewish people can attribute the increase in anti-Semitism to the misdemeanours, real or alleged, of individual Jews is a complete mystery. To fail to see that those who ascribe the faults of particular people to the entire ethnic category to which those people belong are engaged in a kind of guilt-by-association thinking is a form of rank stupidity and a subtle, if unwitting, endorsement of the attitudes of the racist.
This was already understood by Charles Dickens going on 150 years ago. Here is the Jew Riah in Our Mutual Friend:
I reflected that evening, sitting alone in my garden on the housetop, that I was doing dishonour to my ancient faith and race. I reflected - clearly reflected for the first time - that in bending my neck to the yoke I was willing to wear, I bent the unwilling necks of the whole Jewish people. For it is not, in Christian countries, with the Jews as with other peoples. Men say, 'This is a bad Greek, but there are good Greeks. This is a bad Turk, but there are good Turks.' Not so with the Jews. Men find the bad among us easily enough - among what peoples are the bad not easily found? - but they take the worst of us as samples of the best; they take the lowest of us as presentations of the highest; and they say [']All Jews are alike.[']
Gurvitz might like to try catching up with that. (See also this follow-up post of Eamonn's.)
