Riding above

Anti-Semitism, as a political movement, saw itself domestically as riding above all parties and in foreign relations as riding above all nations. By adopting anti-Semitism the parties were able at once to fashion themselves as superior to the institutional constraints of the status quo while at the same time they could organize themselves around the practical matters of politics and not just ideological punditry. 

For nascent, still-building, revolutionary political movements such a catalytic, central organizing principle was a God-send.
