Are there any empirical proof of the assertions he makes about the origins of Christianity? Did slaves really brainwash society into thinking the strong were bad and the weak good? I mean I've seen this shit in everyday's life, so I think he makes a strong point about morality and resentment, but I havent found proof of Nietzsche's theory about Christianity. It just seems to me that he made a psychological observation about the origins of morality and associated it to Christianity.
