Karl Marx was a leftist Jew and Communism was a critique of Zionism, which he calls "Capitalism". Referring to the Jews as the Capitalist Class. Communism - Zionism was the left-right split amongst the Jews of the era, but Marx, being Jewish, wanted to eliminate Race from the equation. So he created Internationalist Socialism which has become a cult that all humans are now waging a global war against in the hopes of preserving their own tribe.
