To call a fight for the Zionist idea of a Jewish nation, for the federal principle of Party organisation, a fight for the equality of the Jews in the world family of the proletariat is to degrade the struggle from the plane of ideas and principles to that of suspicion, incitement and fanning of historically-evolved prejudices. It glaringly reveals a lack of real ideas and principles as weapons of struggle.
