Acts of anti-semitism are justified by an increasing number of "respectable" commentators, who accuse Jews of being the cause of their own suffering. This logic borders on apology of hatred; worse, it is a veiled threat that if Jews fail to oblige, nobody will stand by them in the hour of need. Instead of sympathising with the victims, anti-semites exploit the Palestinian cause to side with the perpetrators. Around the world, only Israel and the Jews earn such contemptuous treatment.

This last sentence, which I have bolded, is not true. In the US after 9/11, Arabs and Muslims received the same sort of treatment from many people. And even now in the US, Arabs and Muslims are the only ethnic and religious groups against whom it is, to an alarming degree, regarded as respectable to practice bigotry and prejudice.

Having said that, I will concur with the article in saying that violence should not be practiced against Jews because of the actions of the government of Israel. Nor should it be practiced against any other group of people because of the actions of other members of their particular group. Collective punishment is wrong in every context in which is appears.
