"Antisemitism is the socialism of fools" basically means that people falsely conflate banker hucksterism and finance capitalism with Judaism.
It's good to hate the corrupt and usurious banksters, it's good to nationalize the banks and wrest them from the shadowy private interests, it's not good to go around harassing and killing some random ethnicity or religion, or promote some stupid idea of "racial purity" as Hitler did (reminder, he shot himself in a bunker after losing to Stalin)
Those with a class analysis instead of an ethno-religious analysis oppose ALL of the bankers — "Christian" "Muslim" and "Jewish" usurers all alike (scarequotes because all those who engage in such practices are going against their professed faith, and are actually satanists — worshiping Mammon and Baal and Moloch)

We Hate MORE of the Enemy than You Do
Nazis only hate SOME of the bankers (the Jewish ones) — while letting the other bankers off the hook
The Bolsheviks CANCELLED Russia's debts
The nazis KEPT Germany's debts, and kept paying the evil banks which initially screwed over their people
Only one is a clear antidote to the "banker" problem
