We have the exact same problem in the left movement, maybe not as worse as within the right, but it's there. Our "jews" are the bankers, managers and CEOs. We give them attributes, like greediness, absence of emotions, hideosity and so on. We reduce their materialist class interest to some shitty human nature moralist stuff. We don't use the term jew explicitly, but this false criticism can function as a hotbed for real, primary antisemitism.
Well, I explained the how so part.
A good deal of the anti-neoliberalism radical left, or born again social democracy, uses the distinction between parastic finance capital and productive capital while being neither anti-judaist (as in, prejudice against a religious group) nor anti-semitic in any way.
Reducing class interest and the particular ways financial capital operates to silly stuff like "greed" can't be reduced to any recognizable form or antisemitism whatsoever.
