confusing thought of the day

right now (well, 5 minutes ago and then as soon as i finish this post), i'm working on a paper on fascism, using the writings of benito mussolini. while reading mussolini, something confused me. he says that fascism repudiates socialism; yet he was happy to join up with the nazi (national socialist) party, who were supposedly fascist. hopefully i'll get an answer tomorrow in class. in the mean time, feel free to weigh in.
