While looking for a reference link to my previous post I discovered this:

A famous negative reply to the issue was penned by Karl Marx, The Jewish Question, (Braunschweig, 1843). He asks the question “The German Jews desire emancipation. What kind of emancipation do they desire? Civic, political emancipation.” And answers: “The social emancipation of the Jew is the emancipation of society from Judaism.” Karl Marx responded to Bruno Bauer’s two studies on the Jewish Question focusing on religious differences by seeing a corrupt capitalist nature to be essential to Judaism, and thus preventing its assimilation.

It’s all the more interesting because Marx was Jewish by birth. So the father of communism, who was a Jew, claims a corrupt capitalist nature is essential to Judaism. It appears Marx wasn’t a practicing Jew but I still find it ironic that he contributed scholarly works On The Jewish Question that contributed to the genocide.
