You're setting up strawmen here. Any belief system will have extremists - doesn't mean that belief is bad. Perhaps we can judge belief systems by the proportion of extremists they produce? Postmodernism and Nihilism don't look so bad in this regard, whereas religious cults, hardcore racists, and Leninists have pretty bad track records. And it's interesting that you call out Marxists, but not fascists, Nazis, and religious zealots. Care to elaborate on that?
