About this “Benjamin” thing. My 2 cents. There was a movie - All About the Benjamin’s. Was it about Israel? Nope Ice Cube made a movie - it involved $100 bills. Benjamins have been lingo for money since I was a kid, so 15 years at least. Unless she also put another reference to antisemitism in that same post/thought - I would directly relate Benjamins to $100 bills.
Life is context. The Right and Left come from different contextual worlds. The right side is dying a slow and loud death. The Left is just starting out (younger) and thus likely where this divide in thought comes from.
