Jews invented communism? The word communism was coined in 1840 by John Goodwyn Barmby in reference to followers of the French revolution era Grachus Babeuf. Marx himself was the son of converted Jews who was himself quite anti-semitic. And 1920s Berlin was one of the cultural capitals of Europe filled with great writers and musicians.
Marx was instructed in communism by Reform Rabbi Moses Hess. See post 87.
