Jacob Zineman in 1923:
“As a convinced Marxist and enthusiastic socialist during the period of my youth, I wanted to forget the harsh, insulting expressions on Jews and Judaism which Marx had penned in his well-known article of 1844 ‘On the Jewish Question’. I searched for all kinds of reasons to justify and excuse Marx’s wholly negative attitude to Judaism.”
Then in Vienna in 1923,
Zineman and “thousands of other pedestrians saw on the city walls of Vienna, bright red posters with crude anti-Jewish Nazi slogans and with authentic (unfortunately!) quotations from ‘what the Jew Modechai Karl Marx has written about the God and religion of his former co-religionists’.”
Zineman:
“Marx’s words in the context of the evil blood-curdling swastika made a deep impression on me.”
