this is the thing that bugs me about nietzsche, this idea that the death of god will lead to all kinds of depravity, and his supposed prophesy of nazism. the exact opposite is true. he lived through the high period of western civilization, and longed for a period of backwardsness - which returned with nazism, via bismarck perhaps, but nonetheless.
and, so, it's true that you see a kind of interregnum of barbarity in the 19th century, but it's precisely because the civilization had done away with christianity. then you see a return to barbarity with the return of christianity, in the form of nazism. and, now, post-1945, you see the death of anti-semitism in germany - because christianity was once again put aside. except that it is still there, and still threatens to return...
the problem is that history is written by christians, so they consistently misunderstand this accidentally on purpose.
