Unfortunately, it is not the only example. While some Jews (especially Herzlians) do internalize harmful stereotypes, it is rare for them to arrive at the extreme end of the spectrum. Andrew Auernheimer, Daniel Burros, Frank Collin, and Patrol 36 are a few instances representing this extreme: they willingly promoted hatred of (other) Jews in spite of their genealogic links to them.
It is easy to laugh at these types for their obvious hypocrisy, but they should not be underestimated. Anton Arco‐Valley, for byspel, gained the respect of antisemitic gentiles (including Joseph Goebbels) by murdering a Jewish politician. The NYT quoted Hans Priwin, a member of the executive committee of the Association of German National Jews, to downplay antisemitism in the Third Reich. Reinhard Heydrich had some Jewish ancestry. I could go on. Pro‐Axis Jews are rare, but they can be no less dangerous than pro‐Axis gentiles.
By the way, it is interesting to compare how the Herzlian régime treated Patrol 36 to how it treats, say, Palestinian children. The Herzlians treated Patrol 36 with far more dignity than they treat even the youngest Palestinians.
