Here’s Sartre on defeating anti-Semitism:

“The cause of the Jews would be half won if only their friends brought to their defense a little of the passion and the perseverance their enemies use to bring them down. In order to waken this passion, what is needed is not to appeal to the generosity of the Aryans- with even the best of them, that virtue is in eclipse. What must be done is to point out to each one that the fate of the Jews is his fate. Not one Frenchman will be free so long as the Jews do not enjoy the fullness of their rights. Not one Frenchman will be secure so long as a single Jew – in France or in the world at large – can fear for his life”
