My big thing for the Jewishness in general, and the control of the cultural entities of the U.S., was noticing way back in the nineties, these random insertions for no logical reason of a character being Jewish in movies or (there might be more of a reason in a big) books.
For movies, it's like, "why would I care if a character is Jewish" or "what's this throwaway line about Jewish doing here?"
It's like an animal, pissing on and marking its territory.
