"Sartre, indeed, blames Christians for the origin of anti-Semitism because they talk of the Jews as the murderers of Jesus. (Yet he destroys the point that he had made by saying in a footnote that Jesus was really killed by the Roman soldiers as an agitator, for, in Sartre's terms, if it could be proved historically that the Jews not the Romans were the actual murderers of Jesus, then anti-Semitism by Christians might be justified.) In his anti-Christianity, Sartre himself appears as the frustrated anti-Semite and treats Christians in accordance with his idea of Christians in general, and not as they are."
