The UCU, perhaps embarrassed over continuing allegations that it harbors a culture of institutional anti-Semitism, has finally agreed to investigate complaints from Jewish members and a torrent of resignations by Jewish academics.
Just kidding! Actually, they just decided to redefine the meaning of anti-Semitism itself, rejecting the commonly held EUMC definition (which affirms the possibility -- though, of course, not the inevitability -- that criticism of Israel could constitute anti-Semitism) in favor of, well, it appears in favor of no definition at all. So I guess it's not a "redefinition" of anti-Semitism so much as an erasure of it entirely -- which, when you think about it, is at least more in line with the UCU's general practice.
The closest thing any of the resolution proponents came up with as a counter-definition of anti-Semitism is "hostility towards Jews as Jews". As was observed, this is a far narrower definition of racism than is applied towards any other group; indeed, it is one that scarcely encompasses any anti-Semitism at all (so long as the speaker can claim to have his one Jewish friend). "I don't hate Black people, just the uppity ones" is still racism. "I don't hate Jews, just the Zionist ones", apparently is not.
Some members complained that the EUMC definition was used inappropriately to suppress legitimate criticism of Israel. Some of these complaints were clearly bogus -- I'm sorry, Sean Wallis, but "refuted utterly" or not, what you said was anti-Semitic under any plausible definition of the term. But even to the extent there were some "bad" allegations made, as one of the few opponents of the motion observed, no definition can, in itself, prevent misuse. The only way we can evaluate the validity of a charge of racism is by assessing it on the specifics -- not by starting with a presupposition that the charge is made in bad faith.
The broader point is this. We have in the UCU a union which endorses a boycott of Israel while praising human rights luminaries like Venezuela, specifically invited a convicted hate speaker to talk up said boycott (and affirmatively refused to disassociate itself from his anti-Semitism), and, faced with a wave of Jewish resignations from the union, elected to celebrate the demise of "Zionist" influence rather than investigate the possibility of a culture of anti-Semitism.
Each day that the UCU continues down this path is a day Eve Garrard's demand becomes more undeniable -- the UCU is simply not an organization that anyone genuinely concerned with anti-Semitism can retain membership in. It is infected beyond salvation.
