they have a self-victimizing trait in their culture where they always want to be seen as victims

I don't know if such a correlation exists. If it does, there may be self-selection going on. A black person will always be seen as black; but a Jewish person has the option to set aside the traditions of their parents, marry a non-Jewish person and identify as white.

Such intermarriage is highly frowned upon. On the one hand, such family resistance against intermarriage is racist. On the other hand, cultural barriers against intermixing are how Jewish identity has survived through the centuries. If the barriers didn't exist, the identity would have long been lost.

A Jew who chooses to continue this identity therefore to some extent also willingly chooses the victim aspects of the identity. This is assuming there is a correlation, which there may be.
