> Jewish victims are very disproportionately represented in hate crime statistics, for example.

There is a very serious issue of reporting here. Someone might report a wrong look as an act of hate, and members of a different community (poor, recent immigrants) can be used to being discriminated and treated with contempt, and never report it.

If you actually check the statistics of "antisemitic acts" that are published (usually issued periodically by Jewish organisations) you will find lots of very small and unverifiable episodes.
