Indeed, the “new anti-Semitism” makes use of two criteria simultaneously. There is the criteria for attaching the label which boils down to most things which inhibit Jewish Zionist power seeking. Then there is the criteria which attaches to the label, namely, hatred of Jews.

The attaching of the label fulfills two functions. First, it is used as an ad hominem attack to discredit a person’s views without actually discussing them. Second, it is a signal to Zionist (and other?) Jews, and perhaps other Zionists, that this person is to be treated as an enemy.
