Here’s an interesting passage on Mussolini (the Italian fascist) and Christianity from Jonah Goldberg’s Liberal Fascism:

Mussolini’s Nietzschean contempt for the “slave morality” of Christianity was sufficiently passionate that he’d sought to purge Christians of all kinds from the ranks of Italian Socialism. in 1910, for example, at a socialist congress in Forlì, he introduced and carried a resolution which held that the Catholic faith—or any other mainstream monotheism—was inconsistent with socialism and that any socialists who practiced religion or even tolerated it in their children should be expelled from the party. Mussolini demanded that party members renounce religious marriage, baptism, and all other Christian rituals.
