The “couldn’t resist” was an expressions of disappointment- the original post was shaping up as a worthy rejection of antisemitism within the Middle East debate – but then we just had to have the qualification at the end. Why? I would compare it to something like: “we categorically condemn sexual violence as a hateful crime, but you have to admit this particular woman was dressed provocatively…” Antisemitism has a long history, and in every historical period there was always a good “reason”: the Jews killed Christ, they are too rich, too communist, too cliquy, trying too hard to assimilate, too progressive, conservative, too cosmopolitan, or too nationalistic. All of this before 1948 (or 1881). Sexist violence occurs no matter how women dress and blaming the victims style of dress or behaviour is always deeply offensive.
One should have the clarity and conviction to condemn both sexist violence and racism without caveat or qualification.
