Karl Marx, the father of the modern Left, in his _On the Jewish Question:_ 


"As soon as society succeeds in abolishing the empirical essence of Judaism, 
which is the huckster and the conditions that produce him, the Jew will become 
impossible, because his consciousness will no longer have a corresponding 
object." 


"What is the secular basis of Judaism? Practical need, self-interest. What is 
the worldly religion of the Jew? Huckstering. What is his worldly God? Money. 
Very well then! Emancipation from huckstering and money, consequently from 
practical, real Judaism, would be the self-emancipation of our time." 


"In wanting to be emancipated from the Christian state, the Jew is demanding 
that the Christian state should give up its religious prejudice. Does he, the 
Jew, give up his religious prejudice? Has he, then, the right to demand that 
someone else should renounce his religion?" 


"Christianity sprang out of Judaism. It has again withdrawn into Judaism." 


"The Jew has already emancipated himself in the Jewish way: the Jew who is, for 
example, merely tolerated in Vienna, determines with his money power the fate of 
the entire German Empire. The Jew who is without rights in the smallest German 
state, decides the fate of Europe." 


"Thus we find every tyrant backed by a Jew, as is every Pope by a Jesuit. In 
truth, the cravings of oppressors would be hopeless, and the practicability of 
war out of the question, if there were not an army of Jesuits to smother thought 
and a handful of Jews to ransack pockets."
